I had a microdisctectomy 3 months ago. Felt great intitially but have had recurrent sciatic pain, which has jumped to the next level. MRI showed scar tissue etc. Dr says he can operate, but has put me on nurontin. Has helped a little.Will this improve, wil TENS machine help with pain and further scarring, i s back surgery the best option and if I can prepare for this one with supplements like collagen and Vit C etc, help with next scarring? Am new to this don't know what the chances are? Thanks for any info/tips.
