Hi Joanne, I feel so bad for your son. And I understand him "walking like an old man". I am a 54 yr old woman. Over the last few years OLD really was what I felt. I feel quite a bit younger now. For the past 3.5 years, I have had bursitis of the hip which for me affects the muscles from the hips, butt & down my legs. I'm not sure if this would help your son but was wondering if you'd checked out the amino acid L-Glutamine. It is primarily sold for body builders to help their muscles after exercising ( helps build proteins and repair the muscle) For the last 7 months I have been taking L-Glutamine. It has really helped me - very little pain now except when I over due. "Talking" with others online regarding bursitis, all say it definitely makes a difference on the company -purity - that makes it. It is sold at health food stores but I get mine online from Life Extension. www.lef.org which I have been told has one of the best quality. I met a lady that specializes in supplements. She felt so strongly that L-Glutamine (from this company) would help me, that she sold it to me at cost. I wouldn't have tried it other wise. I spent enough $ trying things as I'm sure you have too. She recommended that I take 1 tablespoon three times a day. This is in the powder form. I haven't figured out how much that is in mlg. On the bottle the recommended dosage is 1 teaspoon 3Xdaily. I was told that the powder was the best way for absorbing. And that the high dosage was the only way to help. I took this dosage for 5 months, then 1 tablespoon twice a day, & this last month I've been able to cut back the dosage to 1 tablespoon once a day. If I've done too much I take it twice daily for a few days. The site does say it's nontoxic. I could feel improvement in less than a month! I'm still trying not to get my hopes up that it is a "cure", but I'm feeling really good now. I'm still having some pain but it's very managable. I wasn't able to walk more than a block without being in alot of pain. I've gotten my walking up to about 10 blocks on flat land & 6 on light inclines! I'm able to climb stairs!! All this is at a slow speed, but who cares? Atleast now I don't feel 100 yrs old. I only use 1 pillow between my legs at night, still need "my" mattress, & am limited by the amount of walking & standing I can do. But still - I am sooo much better. On other threads quite a few people say "don't have surgery for it!" It can leave scar tissue which can be even worse pain. Also phyical therapy usually isn't helpful. (I did try it, without any help.) I have posted this on an old thread but thought I'd share it with you. I do hope your son improves soon.
