I have been reading old posts about lactic acid build-up in the muscles but didn't see any suggestions what to do about it. When I first developed fribromyalgia some 3 years ago I had a hair analysis test which showed calcium/magnesium imbalance and it was suggested that I wasstoring calcium in the muscles which contributed to the pain. Since then I have been taking magnesium but not calcium and have not noticced any improvement in the pain. Would lactic acid build up cause the twitching and pulling in the fibres near the joints? Would rebounding,/ bouncing help? Nothing I have tried in the last three years has lasted for long to relieve the pain.
