A co-worker who went to a chiropractor for sciatic nerve damage found relief for over a year now and expressed to me his happiness in his greater mobility.  He has had Carpal tunnel surgery 3 times and yet he still drinks soda pop even though he knows the damage it causes to his nerves. Addictive habits are hard to break.  He is a great example of how ineffective surgery can be in covering symptoms without dealing with the cause.
