Chronic Post Op pain after Left Lung Lobectomy Surgery

Has anyone had increased chronic side, abdomen & back pain 2+ years post left lung lobectomy surgery, and/or a protruding bone under the left breast, where chest tube inserted during surgery?
My abdomen is also still numb.
I am 2+ years out from surgery, and my pain is increasing. Pain pills do not even help, even though my dosage of gabapentin has been increased to900 mg daily. I have done every type of suggested treatment with no help. (PT, nerve block, acupuncture, chiro, massage therapy, spine & abdomen MRI, neurologist)
I believe my surgeon performed a sloppy, negligent surgery.

Thank you for any input.
