I have muscles pain for over a year.i even hardly can brush my hair.alot of doctors don't understand my illness.am i the only patient who suffer?

No, and it sounds: Like a form of "functional somatic syndrome", like fibromyalgia. Grind teeth at night and/ or have bad insomnia? Snore badly? Consider treating insomnia with med that helps muscles relax, i like clonazepam, 1-2 mg at night, with an snri, like cymbalta, (duloxetine) mproves pain filter, tramadol may help, has similar function but partial opiod stimulator. Pain and mood are related.Top down approach way 2 go.
