My first advice would be to see your regular doctor. It sounds like a bad case of Costo, but just to be sure, I would go see someone. Have you considered seeing a physical therapist and/or chiropractor. I went into physical therapy to help treat the costo, and began seeing a chiro as well. It turns out that along with the costo, I have a few ribs out of place. Getting those set back in, along with the stretches, ultrasound, etc., from the PT seems to be working. Because of side effects, I generally can't even take the OTC NSAIDS recommended for the swelling and pain, so I've been managing the pain with the help of the people I'm seeing.
It sounds like your pain is VERY severe, though, and may need something more drastic. I know at one point steroid injections were mentioned, although reviews on this and other websites seem to be very mixed on that treatment. Again, I'd see your doc. Even if this is costo, it sounds like you've done a doozy!
Good Luck! And prayers go with you!
