Blood In Stool Underactive Thyroid What Does Blood In Stool And Burning Mean?

What does blood in stool and burning mean? - blood in stool underactive thyroid

I am a 15 years old girl initially all. It is a shame, but recently, after using the bathroom, I burn. Same as 20 minutes after using the toilet, I always burn. Anyone who has been around for a week. Today I found blood in my chair time. And it was bright red, even toilet paper. What does this mean? Should I see a doctor?
