I read your post with interest as I have dibilitating bursitis in both hips since '98. I have eaten 100% raw for 90+ days, so I definitely have not had any sugar. My diet change has enabled me to sleep for 8 hours and I do think the ability to get into deep sleep has helped my joints until this week when I had the worst flareup I have experience. There is no explanation for what brings on these acute attacks. I also cannot exercise and was an avid walker 7 years ago. Like you I have had shots in both hips 3 or 4 times; been to two rheumatologists; two othopedic surgeons. After shots and physical therapy they all say there is nothing they can do. It is very frustrating. I have not faithfully done the stretching exercises so I am trying to follow through on those for next few months. I also wish there was a miracle cure and I have read about the surgery.
My GP recently did Lyme test and I asked for test for gout. I saw on Discovery TV about a young man who was disabled due to bursitis/arthritis in his joints and during exploratory surgery discovered he had gout in his elbow....my tests were negative. You may want to test for Lyme and gout.
