Thank you for your reply Jennifer. I have not checked in on this forum in quite some time. The symptoms I described above have ebbed as of late but I don't doubt they may return, seemingly randomly. I am seeing a new neurosurgeon re my spine and he is taking a look at things, considering surgery, etc. I have for some time had lumbar spondylolisthesis and stenosis.
Lately, I've not thought much about the issues I described in my original post above because I have been preoccupied with different problems–namely abdominal bloating/pain, bowel issues for over 2 months and they are much more significant that my normal IBS experiences.
