I think I read that you had x rays showing the disks sitting on each other? the Dr should have followed up w/MRI after seeing that..
Usually well trained PTs can do "hands on" tests to locate and sometimes pinpoint the trouble areas.
I'd get hat MRI scheduled so the Drs will know what is going on.
(ask for a copy of the report to be sent to you)
If they decide the pain/symptoms do not fit with whatever the MRI does show when you get the results, then they may want to look into other things , perhaps CRPS/RSD.
I hope you are getting copies of all tests & reports in case you need to see many more drs..it's easier to have your own copies..
I think I saw fibromyalgia mentioned in another of your posts also..
I'm sorry I don't know what to suggest for pain relief at the moment..
Did PT places ever try a TENS for you? Or IF stim?
Do they have low level laser therapy?
