The rheumy puts me on pred, when I am in bad flare, but only for a short time, he doesn't believe in a long term pred dosage. When I start with usually 60 mg, tapering every three days, I feel great, but as soon as 5 mg hit, the pain is back. I never take it long enough to gain alot of weight.
I was diagnosed with Lupus and RA in 2006, but added Sjogrens last year, all three are the culpret for pain and breathing problems.
I can understand, that you would like to loose weight, I would do the same thing, but it is not worth it? We ( women) need to put our need to be thin on the back burner.
I hope, you can back to the way, you have been before, with much less pain.
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
