Naproxen
"I have been on medication for 14 months whilst the doctor tried to work out what the pain was. Finally had an MRI and I have 3 slipped discs. Have 100mg Tramadol 4x a day with 20mg Amitryptiline and it has no effect whatsoever. I read about Naproxen and have been prescribed it today.  The relief was almost immediate and I am hoping for my first solid nights sleep in over a year. Fingers crossed."
