Tried several treatments to alleviate

Tried several treatments to alleviate nerve damage by a surgeon that removed a lung lobe. So far these interventions have not releived this extreme pain. I am now migrating from doses of 25 mg of Tramadol to Lyrica (100 mg x 2 time a day..
This transition has been a bit difficult as the pain has become more intense and my ability to function with out pain at this time. I am hoping this transition will work. This has been very difficult dealing with this repercussion I never expected. Obviously this is a very difficult problem and I appreciate their efforts here.
