"i had a brain tumor in 2009 and part of it grew into the thalamus in my brain. this left me with a condition diagnosed as &quot;thalamic pain syndrome&quot;. my doctor had prescribed me some percocet but it was only helping a little. my neurologist put me on some gabapentin as well as nortriptyline. all of these medications helped a little but i was still in pain so my doctor prescribed me nucynta er (extended release). fortunately with the addition of the nucynta the pain has been manageable. i still use percocets as needed but at least the pain is under some degree of control.
