I went through this same thing about 2 yrs ago..
Do you have pain in your elbow?
I had pain behind my elbow and major tingling/numbness in my last {3} fingers.
Sorry i dont know all of your story..
I ended up having ulnar nerve transposition done on my right arm.
It was not an easy recovery..I had to learn to use my left hand for a while!
But i made it through and am glad i had the surgery done..
I still have a stiff feeling in my hand.But no more numbing and tingling.
I have full use of that arm now as well.
IMHO..If i were you.I wouldn't wait any longer.
I cant tell you what you should do,only what i would do!
As for wearing the splint at night.Dont change that!
Also when your on the comp it might help.If your not doing so already.
Take care and let me know if i can be of help to you.
