luvwinnie,
You've gotten many good suggestions for pain relief here. I'm going in a different direction. DH is also on immunosuppresive medication and because of it is now very succeptible to strep. He has had several bouts with it over the years. He actually landed in the hospital and needed IV antibiotics to contain it a couple of weeks ago. He had a raging fever, sore throat and terrible body pain when he landed in the ER on a Friday night. They started taking a whole bunch of tests and we kept asking for a throat culture, knowing it was most likely strep. Sure enough. His doctor (who kind of fluffed off an upper respiratory infection about three weeks prior to his hospitalization) now wants DH to remind him that he's prone to strep ANY time he's feeling under the weather. BTW, he was taking Zithromax (DH is allergic to penicillin) prior to his hospitalization. Apparantly, it didn't do the trick. If you're still not feeling quite right after the 10 days of penicillin, push the issue with your doctor. Strep can be very serious when you're immunosupressed.
Hope you'll be feeling better very soon.
