oh my! what a heartbreak...but at least he has YOU! and believe me, you have no idea (well yeah maybe you do) what a difference just YOU being there makes.
it sounds as though he's going through some intense & acute pain right now; so the 1st thing would be to get the pain & inflammation under control.
the prednisone should help the pain & swelling & inflammation rather quickly; can he use Tylenol?
unmanageable intolerable pain should be treated, can he see a family practice MD? maybe a little stronger pain med like a Tylenol 3 or something until the RA meds start to kick in?
i swear by ice packs too, & a heating pad for pain like sjkly explained.
you really have to do ANYTHING & EVERYTHING you can to get to a comfort level, i know crazy intense joint pain, and have been to the ER for that many of times...
there's only so much you can do over the counter & at home.
i know i respond very well to TOUCH! all my honey has to do is lay a hand over my knee & i swear it gets better (ok a little bit).
but i think your honey needs some pain management. whether it be oral pain meds or patches (LidoDerm works well) and even steroid injections (he may benefit greatly from that).
how is he tonight?
take god care,
