Julie... so sorry to hear about your situation. I deeply empathize w/ your pain, suffering & distress.

i've never had gall bladder surgery but know many who have w/out and also with major problems.

I've had several GYN surgery, not Hysterectomy - for a various problems --poly cystic ovarys, adhesions, and last surgery for fallopian tube problem originally thought to be cancer. Complicated.... but since ,continue to have pain often severe in pelvic area.

Not confirmed but speculation that pain may be from nerve damage.
Hx of adhesions from prior Gyn surgerys..was usually cause of pelvic pain for many years, but last trip to GYN , said he didn't think was adhesions this time. Whatever-- pain persists.

I have tried many things inc. Lyrica, which caused extreme sedation. also Problems w/ Neurontin , Cymbalta & other antidepressants. Other pain meds {narcotics} help--but nothing does when get flares of extreme pain.

I had an infection & hematoma after one surgery years ago. Not nice.
I don't know who may be the best DR for you....

I've been to many specialists-Neuro, Gyn, urologists & surgeons. So many organs in that area plus nerves that could be damaged.

I hope that this does not become Chronic Pelvic pain or any Chronic Pain disorder but, seems may already be. Perhaps others can share more at forums on chronic pain or gyn & women's issues.

My heart & prayers go out to you...
