Hi I got an allergy shot a few months ago and started feeling moody and tired. I kept having hot flashes and head aches. A week and a half ago my symptoms started getting much worse. I now have severe upper back, neck, joint and right shoulder/arm pain (where I got the shot). I'm also experiencing extreme weight loss, fatigue, weakness, anxiety attacks and horrible migranes. My doctor has no clue whats going on. PLEASE HELP!
