Am a golfer and we are experiencing cold weather in kenya africa.what is the course of pain in my right humerous bone.

Humerus pain: No idea based on your description. What part of your upper arm is it. If close to your shoulder it may be your neck, rotator cuff, ac joint. If distal near the elbow if may be from you neck, nerve from your neck, your elbow, or the bone itself. Could you provide more information like, exact location, how long it's been there, what makes it worse, better, ever had before, numbness or tingling?
