Suggest Treatment For Extreme Pain Due To Overlapped Muscles

My daughter is 20 years old, has hereditary spheral cytosis, and has been suffering for the last year and a half with extreme side pain. She has had an MRI at a sports medical clinic, where the doctor told her she had a muscle lapped over one of her rib bones. She has been in and out of the hospital and doctor s offices, but so far no one can find out what is wrong and they don t want to operate. She is getting tired of the pain, which tends to flare up when her stress level increases. She doesn t want to be on pain medicine she just wants relief.
