I have used chiropractic successfully for years for different problems. But I wouldn't see Dr. Birch because he doesn't hold a license in Mexico. He hasn't done his service to the community/country and won't get my support. I want someone who has done things legally and done his service period like an honest person.
How do you know it's your sciatic nerve and not your femoral. Both affect your hip and one the back of the leg and the other the front. At a certain age deteriorating disc disease affect a lot of people. I agree with El Salto 100% on seeing an ortho surgeon but let them decide what diagnostics.
