I also was a sceptic about chiro's, about two years ago I was having awful headaches, I had a catscan and saw eye doctors. All tested fine. Then I went to see a chiro and started getting regular adjustments,headaches are gone and I feel much better. I feel worse when I dont go to see him. Read up on the practice. It all makes sense, the spine is the Highway to your body. If it is functioning poorly,you function poorly. Definetly go see one. Pain down your leg is from a nerve called,I believe, the sciatic nerve, (excuse my spelling), which also explains your numbness in your foot. Let us know how you make out.
