Thanks everyone--
Yes, the Humira has been wonderful, and I'm trying to find a way to keep using it, but it's looking doubtful. I'll be in Boston, and they've recently passed the insurance requirement law which has in turn created all these odd rules and regulations for purchasing insurance. Pain-wise, I can go back on the NSAIDs, but I'm afraid they're going to wreck my stomach & GI track again.
And I understand the entire painkiller thing, wanting to avoid them, control them, etc. Unfortunately, up to now, they've been the most effective.
I will look in to both the TENS unit and the naltrexone. Thank you, fellow AS-ers!
Oh, and I will be in Boston for international studies. I'm a big travel junkie.
