HI Steff!
Gosh you sound SO miserable! Your pain must be dreadful! I sure feel for you! I know how frustrating it is to not know whats causing the pain and just continue to pay dr.s and do tests without good results!
It does sound like the surgeries you had have caused damage to your nerves. I hope your dr. can figure out some pain meds that will help you. Maybe you need the epidural or some other the "spinal cord stimulation" that I saw in a pamphlet at my dr.s office. They run a cpl wires up your spine and send electrical stimulation up them......sounds similar to a TENS unit but internally. It's for chronic pain. Sounds like by this point you are ready for any type of procedure that will end this pain.
Take care.......Hope your Sunday hasn't been too painful. Thinking of you........
