I am going riding in the quantocks on wednesday and have heard that there are lots of ticks on the hills and there is a possibility of getting a tick and catching lyme disease :shock: . Has anyone else heard of this and will I have to protect myself while riding by leaving no bare skin(this would be awkward)? I don't really want to worry but is it a problem?
thanks.
thanks.

What is Lyme disease?
Borrelia (Lyme disease) is caused by an infection resulting from a tick bite. The tick often buries its head into the skin.
Lyme disease is an infection that derives from a tick bite. The disease has a variety of symptoms, including changes affecting the skin, heart, joints and nervous system. It is also known as borrelia or borreliosis.
What causes Lyme disease?
Lyme disease is caused by an infection from a micro-organism (Borrelia burghdor feri), itself transmitted by a bite from the wood tick, a blood-sucking parasite which normally lives on deer.
The wood tick is found in many areas, particularly in forests where deer are common. A tick will settle anywhere on a human body, but prefers warm, moist and dark places like the crotch or armpits.
When the tick has found a suitable place on the body, it sticks in its probe to draw up blood, exposing the host to the risk of infection.
What does Lyme disease feel like?
Simply seeing a tick somewhere on your body does not mean that you have contracted Lyme disease. Unfortunately, not everyone knows when they have been bitten, so consult your GP if you detect the following symptoms.
A red spot around the location of the tick's bite. The spot will gradually grow bigger, often with a pale area in the middle. This symptom is called erythema migrans.
Erythema migrans can also appear at other places on the body where the tick has not bitten. Some people get many red spots.
Usually one to four weeks will pass between the bite and when erythema migrans appears.
Some patients with Lyme disease feel like they have caught influenza - the symptoms may be:
drowsiness
headaches
mild fever
joint and muscle pains
swollen lymph glands.
What complications may occur?
Acrodermatitis chronica atrophicans
This is a condition that often develops in older women. Several years may pass from the tick bite until the development of this phenomenon. The symptoms usually involve changes in the skin around the tick bite, such as:
swelling
bluish or reddish discoloration of the skin.
Neuro borrelia
About 15 per cent of people with borrelia develop so-called neuro borrelia, between one and five weeks after the tick bite. The central nervous system is affected and the symptoms that result are very mixed and not specific.
The symptoms often begin with back pain, typically between the shoulder blades and in the neck like a slipped disc. The pain worsens at night.
Distorted feelings around the area of the bite. The nerves become numb, especially in the face. This may occur at any time up to four weeks after the pain began.
Sometimes neuro borrelia may present itself as meningitis, with fever, headache and stiffness in the neck.
In rare cases, the disease may become chronic, with a slowly developing destruction of the nervous system, numbing, partial hearing impairment and the development of dementia.
Neuro borrelia demands immediate treatment, usually with an admission to hospital.
Inflammation of the joints or Lyme arthritis
This condition may present itself in days or, rarely, years after the bite, but it is very rare. The inflammation of the joints causes pain and swelling. Often, only one joint is inflamed and, rarely, more than three. The most commonly affected joint is the knee followed by the shoulder, elbow, foot, and hip. It has symptoms similar to arthritis.
When treated, the swelling will go away in about one to four weeks but it may return in later months or even years.
Effects on the heart
Lyme disease may cause:
inflammation of the heart tissues, along with arrhythmia
heart failure may develop in severe cases.
How does the doctor make the diagnosis?
A diagnosis of Lyme disease is more likely if the patient remembers a tick bite and presents the doctor with the erythema migrans rash.
To make a firmer diagnosis the doctor may take a blood sample to determine whether the patient has developed an antibody towards Lyme disease in their blood.
Antibodies can typically be found between two and four weeks after contracting the disease, but sometimes the antibodies do not appear for up to eight weeks. This means that people may have Lyme disease even if antibodies are not present at the very early phases, so repeat tests may be necessary in order to detect the diagnostic antibody response.
On the other hand, a positive antibody test does not necessarily mean that borrelia has recently been contracted. The antibodies may be found in the blood several years after an infection is over. Unfortunately, the antibody test is not a very efficient diagnostic tool: false-positive results are common.
If the doctor suspects neuro borrelia then hospital admission is required for tests on fluids from the spinal canal. This is to determine whether Lyme disease has entered the nervous system.
In cases of chronic neuro borrelia the treatment may include a CT scan of the nervous system.
Possible further development
With immediate and appropriate treatment the erythema migrans rash will often disappear within two weeks. Even without treatment, most cases of erythema migrans will go away without leaving permanent effects. But treatment lessens the risk of later symptoms in your nervous system and joints.
If the nervous system, joints, or heart are affected, two to three years may pass before the symptoms go away.
In rare cases a chronic disease with permanent symptoms may develop. This may happen several years after the tick bite.
What can the doctor do?
In the early stages (erythema migrans) oral antibiotic treatment may be sufficient.
If there are other symptoms, he or she will arrange hospital admission for further investigation and possible further treatment with antibiotics.
Medical treatment
Medicines used against Lyme disease include:
oral doxycycline (eg Vibramycin) (except in children), amoxicillin (eg Amoxil) or cephalosporin antibiotics are the usual first choices.
when antibiotics by injection are being given, then benzylpenicillin (eg Crystapen), cefotaxime (Claforan) and ceftriaxone (Rocephin) are the usual choices.
no particular choice and method is superior to another - the decision is made by the infectious disease specialist and is dependent on the individual circumstances.

I would say if you wear some sort of padded short with thigh grippers then you are unlikely to ticks in those, ahem, 'delicate' areas. As with leeches, check often 'down there' and under your armpits.....
No worries!0 -
meh, ive been riding thetford (which also has ticks) in shorts for ages and never see a tick nor ever heard of anyone getting bitten by 1.0

There's a knack to getting ticks out. If you try to flick one off, pull it away, smother it with something like vaseline or attack it with a lighter you're asking for trouble. Either the little bugger will panic and regurgitate, injecting you with a load of goo or you'll pull the body away while leaving its mouth parts attached.
To remove them safely you need to grab the head with a pair of needle nosed tweezers, or use a special tick removal tool like the O'TOM Hook (Tick Twister).
Oh, and when ticks get on you they climb UPWARDS and have a fondness for areas of the body with folds of skin. :shock:
As far as Lyme disease goes I'd advise anyone who gets bitten to read up on what the symptoms are and just be aware of them. Any doubts at all and get yourself to the doctors sharpish.
I'm not an expert or anything - a couple of weeks ago I found one of the buggers munching on my arse after one day in the Lake District so I did a little research.0 -

II've been out 4 times this year. Take a look at my leg.

Lime disease does take some time to transfer to the host (you) tho - check out insect repellents for their effectiveness against tics and spray well. Once it gets in to your system tics will drop off you as soon as they get a taste, without a good long meal the amount of bacteria transferred in to your system is easily dealt with by your body's natural defenses.
Even if you do get lymes all it means is a course of antibiotics, which you can drink on, and a few days feeling like you have flu. Not really that serous and probably equal in symptoms to catching a chill out on your ride. But do beware, go see a doctor if symptoms develop! It's only if it's not treated that it becomes a bugger.
The pic was taken in the early stages will post another showing the 'bullseye' if i can be arsed (plenty of pics on the net).

My friend had one on him when I was there a couple of weeks back. We managed to remove it and use some antiseptic cream before it latched on properly and he was fine.Giant TCR advanced 2 (Summer/race)

Thanks for all the information and that tick bite looks really bad Dave.0

Best thing to do is have a bath after your ride and check every inch of your body. I was brought up in the Scottish heather among sheep and would have to pull out half a dozen ticks at a time after rolling about in the heather. As far as I know Ive never had Lyme's Disease but then maybe I've got resistance to it having been eaten so often by the pesky things. By the way a bite shouldn't look that bad - if you pull them out properly with tweezers they don't normally flare up like that.Commencal Meta 5.5.1

University of Sydney Department of Medical Entomology recommends against attempting to mechanically remove the tick, but instead smother it in an insect repellent that contains pyrethrin or permethrin:

That's for Australia's especially nasty tick, Ixodes holocyclus, which can cause paralysis and death all on its own.
If memory serves, deer ticks are smaller and harder to grip to pull off. A chemical attack should therefore be even more appropriate.John Stevenson0 -
From a gp friend, there is a very very very VERY slim chance of getting lymes from ticks in the UK; she has not seene a single case in her life here.
So... CALM DOWN EVERYONE! Just pull the buggers out! I've yanked out dozens with my fingers and so have others that I knkow. This is all hyped up.Crushing the symptoms0 -

Well I didn't pull anything off, its just gone that way which is one reason they think it may well be lymes (though I did scratch it at first, hence the uber scab in the middle).
Apparently the lynes rash can spread half way across your body.Fat bloke, on a nice-ish bike.0 -
I have now come back from the quantocks and i had a great time, while recieving no ticks after two rides. Nothing to worry about0
