Hi,
Have you had these symptoms before?
It is unlike that flexeril or cyclobenzaprine is causing your symptoms.
'Common side effects include drowsiness, depression, headaches, dizziness, and blurred vision. Other side
effects are respiratory depression and decreased functionality in various muscles. Long term use has been
associated with vision damage. Another side effect is dryness of the mouth. Agitation is a common side effect
observed especially in the elderly.'

Sertraline is known to cause diarrhea and microscopic colitis.

You would need to consult your doctor to rule out parasitic infections, crohn's disease, hemorrhoids,
irritable bowel syndrome etc as the cause of your symptoms.

Why was the colonoscopy done?
This could be dysentery too - amoebic or bacillary.
'Amoebic dysentery is well known as a "traveler's dysentery" because of its prevalence in
developing nations, or "Montezuma's Revenge" although it is occasionally seen in industrialized
countries. Liver infection, and subsequent amoebic abscesses can occur.'
'Bacillary dysentery is mostly commonly associated with three bacterial groups:
* Shigellosis is caused by one of several types of Shigella bacteria.
* Campylobacteriosis caused by any of the dozen species of Campylobacter that cause human disease
* Salmonellosis caused by Salmonella enterica '
