First, understand that I am not a medical professional, and nobody can diagnose you without seeing you. Please go to a doctor to make sure. If you are nursing, it could be mastitis. An infection that can be easily treated with antibiotics. You need to get to a doc right away. Mastitis usually starts as a clogged duct, then advances into infection. I've had a clogged duct before, and it was incredibly painful. (Like you said, just wearing clothing hurt! I'm sure your pain is awful. Hang in there. Good luck, and get well soon. This will sound crazy, but putting cabbage leaves in my bra for 20 min intervals (cabbage, pump, then put on warm cloth) helped my pain. Apparently, the cabbage reduces the engorgement, but left on too long can deplete your milk supply. I must caution you that I did not have an infection, just a clogged duct. Another resource is Busom Buddies, a nursing support group that has nurses and lactation consultants on call. If this is nursing related, they can give you ideas to make you more comfortable.
