Ok friends - I have been suffering with this CRAP for over 15 years, Idiopathic small fiber PN - I've been on Lyrica and Oxy for many years and have adjusted to my life. I'm always tired, dealing with constipation and have to monitor my daily activity. BUT every couple of months my right arm swells up and just plane ole HURTS. It feels weak like if it was a leg and I have walked way to much. Usually it is three or four times a year, but it is getting more often and I have to saw I am so over more pain! Anyone have this type of a thing?? Oh and typing is the worse thing I can do - so this is short. Any ideas. To make matters worse I had skin cancer on that shoulder about two years ago. So the removal of the cancer, and the radiation also flared it up even more. BUT I was in one of these flare up's when the cancer was found and have had them years prior.... HELP
