I am a 55 year old female who has had 2 spinal surgeries for neck and lower back and have small fiber/peripheral neuropathy. I am quite experienced with spinal stenosis, degenerative disc disease and osteoarthritis plus working with neurologists/spine specialists and reading MRIs.

To me, it sounds like some nerves may have been impacted when they did your appendectomy. They may also have moved you during/after surgery in a way that disrupted your spine/pelvis/hips.

Did you have MRIs of your cervical/lumbar/pelvis/hips? Your cervical spine can impact your lower body, too. Did you read all reports from your MRIs to see what they say? I have found things my doctors missed/dismissed that were serious (like spinal cord flattening/stenosis which is a spinal cord compression injury that can cause permanent damage/disability). Did you get EMGs/nerve conduction studies of your lower body to see if nerve health in legs is okay? You can have back/hip/leg/foot pain/weakness/numbness coming from your spine even if EMG shows leg nerves are “normal.”
