I am on Ultram ER 300 mg. daily; also hydrocodone(10/500 mg. x4 per day) and neurontin(2400 mg.). I am surprised the PM didn't prescribe neurontin or Lyrica for you, as that is the med that helps my "burn" calm down.
It is a roller coaster ride;however, you should feel free to contact your doc and share that you are still having intense pain and your doc hopefully will address your pain issues.
Hang in there, you have a great support system here on NeuroTalk.
