I had spinal surgery in 2015 for STENOSIS at L3/L4,
Neurological examination is the key for a correct treatment.
Hello and welcome to "Ask a Doctor" service.
I have read your query and here is my advice.
I see that you obtained several opinions from spine surgeons mainly related to the MRI findings.
In my opinion, in your case is necessary a careful neurological examination before to decide the treatment possibilities.
This is necessary to see if the main problem is at your cervical spine, or at your lumbar spine and this information can give only a detailed neurological examination.
Besides this, dynamic x-rays (flexed, extended and neutral position) of your lumbar spine are necessary to evaluate any instability.
When it comes to arachnoiditis, my opinion is first to treat it with corticosteroids.
If the decision will be again surgery, posterior decompression, and fusion in your lumbar or cervical spine is an appropriate possibility with fewer complications.
Stimulators are used after all other possible treatment ways are exhausted.
Hope you found the answer helpful.
Let me know if I can assist you further.
