Elbow pain

jamie1012

I just did a fairly leisurely 25k ride and was feeling pretty relaxed and started a somewhat fast descent riding low on the drops and felt a sudden sharp pain in my left elbow that caused me to start turning left and nearly made me crash. It was a traffic-free road with a good surface so I wasn't tensed up or gripping tightly at all, and hadn't made any unusual movements to cause it, so it freaked me out a fair bit. I'm a beginner, so if anybody has experienced something similar and can tell me if I'm making some rookie error in my positioning then let me know
