Things going very wrong after Dynesys

[LC in UK]

Had cervical osteophytes diagnosed in 1983, not aware of any problems with thoracic spine.
Heard my consultant tell the registrar on Tuesday that my case was "complex". No doubt of that after 4 ops!
Have noticed the muscle spasms loosening up considerably today, whatever was causing nerve compression over the last few weeks seems to be resolving, although I'm not out of the woods by a long shot.
My knees are not so swollen either, very strange? Grateful for the letup tho'.
Desperately need to get exercising again, especially for my thighs but frightened of upsetting the knees!
What to do?
Will definitely let you know how the spinal probe goes.
Thankyou Mark for writing,
Kind regards, Lynette
