My sciatic problem is being taken care of by Radio Frequency Ablation. Basically they burn the nerve that is causing the problem. I have had it done twice and it has helped. While it is not the cure, it does give me relief for long periods of time. Up to 8 months for me...but for some only one session is needed.
Trust me I don't recommend this lightly since this is the next step before invasive surgery.
I have done the meds route, chiropractor, massage, accupuncture, physical therapy, facet injections, trigger point injections and none of them worked. So I am at the most radical of outpatient treatment.
There are plenty of options, you just need to find the one best for you.
