Hi Mick
I have had this problem since diagnoses with my left hand/elbow fingers. the ulna nerve travels tthrough to the 2 fingers middle and ring and I have pins and needles and drop things with muscle cramping etc. I was driven crazy by this it is a constant. Anyway I tried resting hands with splints as I get a lot of swelling around the wrists and it seems to be eminiating from teh ulna joint and then from teh elbow down. My fingers have not been numb.
My previous rheumy sent me for nerve tests and they came back fine. Finally, At my my consultant sked me if i have a habit of leaning on my elbows and that causes it. So since I stopped resting on my elbows I have been lots better. (touch wood and easier said than done). Why it took more than 20 months for this suggestion is beyond me.
My consultant also said that the though the operation is small it does not always work.
So stop leaning on your elbows reading this....
Seriously, If that doesnt seem to be your problem then going back with your questions seems an excellent idea. I hope you get sorted soon.
All the best
Mari
