Yours is a post spinal fusion
status ( operated twice) and now have developed sharp pain
, burning sensation and spasticity
of lower limbs.
At the first place were you operated upon at the same spinal segment twice or it was different segment? What the spinal segment? What was the cause - Intervertebral disc
prolapse or tumor?
Surgeries usually are taken up in cases of intervertebral disc prolapse when all other conservative managements fails or when there is a severe spinal canal
stenosis. It is also not uncommon to land up with a 'failed back syndrome' in post operative cases.
Whatever the case now you need to get the following investigations done:
1. MRI Lumbo-sacral spine (plain).
2. X-Ray lumbo-sacral spine (AP and Lateral)
See a neurosurgeon with the report and get a proper neurological evaluation done.
As for the present treatment options, it is possible only after getting a detailed history regarding the previous surgery , seeing present scan reports and doing a clinical evaluation .
