Hi welcome to healthcare magic forum. Central sensitization and fibro myalgia
are though not synonyms they are inter related with each other. You are lucky that aqua therapy is giving you some relief.
Though it is a difficult disease to treat i suggest you some diet recommendations to have a relief by natural way. avoid taking potato , other tubers, tomato, beans group, coconut, ground nut, egg, chicken, and sea foods completely for a month. If you get relief to some extent, continue the abstance for ever. If no relief continuing taking these foods.
The disease being neurological avoid psychologicl tensions, family problems, and exposure to direct sun light , viewing T.V for longer time etc.
Wishing for a comfertable and happy life and thanks for calling .
