Frustrated with Drug Interactions

I have carpal tunnel syndrome in both wrists.  I'm at the beginning of a flare-up right now.  I am on lithium so I can't take any NSAID (ibuprofen, naproxen), and I can't take a corticosteroid (prednisone) after I had a psychotic break while on prednisone.

And those are the only medications recommended for carpal tunnel - from the Mayo Clinic website.

I started taking some Omega-3 since it is supposed to be a anti-inflammatory, but I know it takes a long time to start working.  I don't know how long.

I can't have grapefruit juice - no fresca soda!, no alcohol, no benadryl(!!!), no...  no everything.  Frustrated.  Taking solace that I can take Tylenol. 

Have you seen an orthopedist? I work for one, and she treats lots of patients with carpal tunnel. She often recommends steroid injections (which I know you can't have). Night splints can help, though. You could also consider surgery for carpal tunnel release, which might clear up the condition.
