I am pretty tender skin wise also. I screamed out in pain when the Chiropractor tapped me with that little thing that dr's have to test reflexes. I hate the blood pressure cuff at the dr's office.
I am sorry to hear that you are having so many medical issues at such a young age. Many of us who have fibro look back over the years before being diagnosed and realize the problem had probably started a long time ago.
My siblings couldn't figure out why I didn't like to be ticked in the ribs. I'd say because it doesn't tickle it hurts. I've had to give up wearing underwire bra's due to rib pain. My skin can be so sensitive that I can't stand a bra strap on my shoulders.
Part of me thinks I'd like to get a massage but the times when I've had them done it hurt for days afterward; like a bruise with no bruise...
I am still working on finding a good doctor who can work with me on a treatment plan. I have to do something to get the pain under control because it is wearing me out physically. That is the key thing I think....make sure you go to a good doctor.
Hope you get to feeling better. Sending hugs your way
