Thanks.

Do you have carpal tunnel? I ask because when carpal tunnel is active in the wrist, it can refer up that radial nerve and cause alot of aching pain.

I have had shingles down that nerve many years ago too. And I was having alot of trouble with it in the summer and on vacation.
As luck would have it...I sprained my hand opening a jar...OH, it set off my old carpal tunnel horribly. So I started wearing my wrist splints (which I always keep around for the past 30 yrs, in fact), and wore it every night and also a home when we came back. The hand improved after a week but I kept wearing the brace anyway.
(I had enormous carpal tunnel when I was pregnant 32 yrs ago, and while it resolved mostly, it is still there a little and flares now and then). Well, wearing a splint again, seems to have fixed that arm pain quite nicely! So I am continuing the splinting every night to see what happens. I just bought a new one on Amazon, and found their prices about 1/2 of CVS's ! I have a new Futuro short style.

I find this style more comfortable than previous ones I've had over the years!

So if you have pain over that radial nerve, think about the wrist being a culprit!
