Pain in right elbow/upper arm?

Lately when I golf I get a pain in my elbow/upper right arm. The pain really varies, sometimes it's sharp and sometimes it dull. Sometimes I get a pins and needles/numb sensation afterwards. It's a hard feeling to explain but I was just wondering if anyone had any suggestions on how to stop the pain or what it could be. Today after my round I put Tiger Balm on it an it helped for now. Thanks for any advice!
