This could be caused by a few problems. You could have thyriod problem, or for some reason that arm is not getting as much blood circulation. Take a fish oil suppliment and it will help with blood flow.
I got the same problem! please help. Especially when I am sitting and using my PC!
Thanks for the info. I'll check it out with my doc. Forgot to ask him about it last week when I saw him.
Maybe getting a vascular workup is in order. Since it is limited to one arm runbiker, I think this is a good thing to start with to make sure there are no blockages. Also if that does not help, they maybe could run rheumatological tests at your regular physician's office. Does your arm/hand turn colors? Does it ever get cold even when you are really upset or stressed out? I have Raynauds. Both my fingers and feet turn colors, but this is even when I am inside the house. I think this is something you should get checked out soon, to make sure your circulation is ok. Good luck
The same thing has been happening to me and only during winter and whenever the outdoor temperature drops below 20 F. Above 20 F I am okay. I also experience this when I am indoor, not outdoor. Any comments?
