It all depends on what is causing the numbness. Are you diabetic? If so, this could be diabetic neuropathy in which case I would see a neurologist for a definitive diagnosis. Other case scenarios would be vascular problems, i.e., lack of sufficient blood flow or chemotherapy induced neuropathy if you are being treated for any type of cancer. If any of these apply find a chiropractor that is proficient in the KLaser neuropathy treatment protocol. We use that in our clinic and it has shown to be 90% effective.
If none of these apply, it could be a disc problem or if you are having urinary and bowel problems along with the numbness it could be cauda equina syndrome which is very serious. I would first start with my M.D. to get a referral to a neurologist and go from there.
Yours in health,
