Can't use my right hand...

Well, first off... I would see a doctor or PT. If you have pinched a nerve, don't mess around with it.

I had a pinched nerve in my neck (I think at ~C5/C6?) and had almost exactly the same issues as you. Loss of feeling, loss of dexterity, pins and needles up and down the arm. It took me nearly a year before I was back to 100%, and even now there are things I know I can't/shouldn't do.

Things that helped: Making sure I wasn't straining my neck (looking up was a BIG thing - no more painting ceilings or installing overhead lights!), maintaining good posture, neck traction to relieve the pressure, working on core strength and massages to help relax my neck/shoulder muscles.

In the short term, you may find some relief with the ice/ibuprofen regime. It didn't help me, but might be worth a shot.

Good luck!

I had a similar problem, though not as pronounced (it went away after a couple hours) from pressure on the hands because my bike was too large. I could imagine you just have it worse - Especially if you are riding for 30+ miles with tingling hands.

Raising the handlebars with a higher angle stem helped.

Whenever I see anyone shaking their hands I feel so sorry for them.

+1 on stretching your neck and shoulders. also +1 on getting it checked out if it doesn't improve quickly. hand issues can start anywhere from the spine to the actual location of the pain. Usually it's closer to the spine. Stretch anything that feels better by doing so - but proceed SLOWLY and GENTLY. They body, especially when under stress will protect (tighten) an injured, stressed area if you try to stretch to quickly or forcefully.

I hope it's already feeling better!! Ice is your friend.

My guess is the Ulnar nerve. I pinched both of mine at IMAZ in 06. It was horrid. I had claw's for almost two months, tho it did eventually get better.
Ironically I had scheduled my yearly "womanly" doctors appt for the week after Ironman, so my doc checked me out then. Said there wasn't anything I could do. She also warned me to change my riding style/position.
I'm very careful now.
