As sometimes repeated emotional trauma and stress causes persistent pain which is no more after few years..
Good question…I have been diagnosed with CFS…with probable fibro pain especially in my chest. I constantly wonder how much of the latter is anxiety driven. My thought are that it is real however anxiety makes it much worse…it adds a layer or two especially when bad.
Your pain is still there or recovered? I have wide spread pain and CFS too. My doctor says I have Fibro, but I do not believe that. I always think my thyroid has problem.
