I have upper chest wall hard swelling to collarbones aches skin hurts

I have swelling on my upper chest wall almost like breast implants, but it goes clear to my collarbones very hard. I get skin pain that just hurts and achy. It lasted 6 to 7 weeks this last time no fever but you can barely touch myself. It hurts so bad on my skin, but the chest swelling is so weird like someone put a pad of hard on
swelling up across from my nipples up to my color bones.
