Hello - thanks for asking your question.
You note lumbar and flank pain after having hysterectomy. Colonoscopy was normal. Please note that without examining you it is impossible to say what is going on.
As I am not a surgeon, my experience in post-op hysterectomy complications is limited. In my internal medicine practice, I have not had this particular scenario before.
There are several considerations. Adhesions may be a possibility. Typically, they present with crampy abdominal pain associated with nausea, vomiting, and abdominal distension depending on the severity.
With the surgery, it is also possible that there may be some residual nerve irritation causing discomfort.
In terms of followup studies, I would suggest an abdominal/pelvic CT to evaluate for any evidence of obstruction, inflammation or abscess. If there is continued lumbar pain, you may want to consider a lumbar MRI to evaluate any damage to the spinal canal or a neurology referral.
Followup with your personal physician is essential.

Back problems can be worsed by any surgery on the belly, because the belly muscles have a lot to do with support of the back. I'd consider an evaluation by a back specialist (either orthopedist or physiatrist -- a physical medicine doctor) before having more belly surgery.
I am going through somewhat of a same problem. I had a c-section in July. Previous to this I also had 2 laparoscopies for endometriosis. I feel I have not been the same ever since. It feels like either something must be wrong with my insides or scar tissue. I also feel like I have a constant air pocket & inflammation. I too wonder if something was damaged between all of these surgeries. It is very unsettling at times not knowing exactly what is going on in my body. Keep us posted after your next surgery.
