pain
"Tramadol works for me.  I've been suffering cervical neck pain for years.  Tried physical therapy, had an MRI, cortisone, facet neurotomy x2.  The second neurotomy didn't help.  Started tramadol and it takes all the facet pain away.  I still feel other pains but all spine related pain is gone.  Minimal fogginess.  I'm allowed up to 400mg per day but usually take 250.
As far as I'm concerned it's a wonder drug."
