Hi,
Sorry to hear that your feeling so poorly. Marty has both AS and fibro. His pain is mostly in his neck. His rheuym said that his pain is more from fibro than the AS.
On the advice of Darrel, I stated putting magnesium powder,630mg, in Marty's pancakes. Within three weeks, he started having his first "good days" in at least a year. He even smiled a couple of times-I mean- real smiles.

It was so good to see. Then he said that the magnesium changed the taste of the pancakes so we went to capsules. He has to take 4-5 capsules to get the same dosage. Because he is not very compliant with meds, his dosage dropped off to 125mg/day. Then came two straight nights of continuous leg cramps. I can't find any capsules at 500mg or more so I guess I'll just have to nag. Magnesium has helped him more than any muscle relaxent so far. Hope it can help you too. Take care.
