I'm done. I can't go through another test, or see another doctor. As a "take the bull by the horns" type of person, not knowing what is wrong is killing me. I've been living with pelvic pain, neck pain, lower back pain, burning sensations in my legs, sharp shooting pains in my arms and armpits, discomfort under my left breast, breathing difficulties, sinus drainage (not infection) down the back of my throat, headaches, night sweats etc., etc.
