Something bloodish in stool and toilet paper

Hi to all, before all I want to inform you I suffer from anxiety disorder (and small depression) and I am on medication for this (bupropion). Recently 2 weeks ago, and exactly after the end of summer vacations I started having changes in bowel movements , more often to toilet with looser stools , and lower abdominal pain. My psyc said it might be the start of IBS syndrome and put me on amitriptyline. What worries me most is that yesterday after a bm I noticed lots of red small pieces on stool(almost diarrhea),, it must have been tomatoes skins when I scanned ,,,but what's scary when whipped with toilet paper there was a tinny red (like pinhead and red like runny nose), that when squised soft into paper it painted it red!! I think only blood can do this! it's soluble in water. Can food (tomatoe) paint-like the paper.

I ll get an appointment with gastroenterologist for sure .

Fyi, recently I was almost 20 days on antibiotics for rebounding strep throat. Symptoms occurred almost a week later.Anyone relevant experience ??thank you

It could be tomatoes if you have been eating them.  Other possibilities are fissures or haemorrhoids.

I agree with pippa. If stool is red it possible hemmoriods. But if it comes out black you possibly are bleeding internally. Anti depressants and other one similar can irritate stomach and intestines. If you don't have luck there are so many anti dependents that are less troublesome to your symptoms. I was on wellbutrun SR. NO BAD SYMPTOMS. TALK RO YOUR PSYCHIATRIST ABOUT YOUR PROBLEMS. GOOD LUCK HOPE YOU GET HELP.
