"i have been taking 5mg norco every 3-4 hours during the day for nerve pain that resulted after a total knee replacement  which was three yeas ago. it has been very helpful and i am able to function which i could not do with a pain level of 8 plus. i have not had any side effects except for constipation which is managed by taking swis kris, a herbal supplement. they say norco is usually not helpful for nerve pain, but it helps me."
