Background:I'm 17 years old, female. I've always, always had stomach issues as a kid, I'd always get horrible stomach aches and always have diarrhea. I would tell my parents about it but they didn't really know what it was and I was basically fed pepto forever. I went to a doctor around the age of 13 and told him about my stomach problems but he didn't do anything, and when I was about 15 I finally saw that I was diagnosed with IBS but they never told me that, I always just thought must have it, but never knew till then. Last year my grandpa went to the hospital for stomach problems and they found out he had Crohns. When I get IBS stomach aches, it comes out of no where most of the time, and hits me hard, My stomach just feels so bad, and sometimes it's like if I don't get to a bathroom asap I'mma have an accident bad. The pain is so unbearable sometimes and at school it's even worse cause I don't have anywhere to go to relieve myself, about 90% of the days I've missed school where due to stomach aches. And the diarrhea is always different like I've read is common with IBS, I could be in there for 5 minutes or up to an hour or more if it's really bad. About a year and a half ago I went to the emergency room from severe pain in my lower stomach area and I had to get an ultrasound and they couldn't find anything but assumed it was an infection in my intestines, and ever since then the stomach aches caused by IBS have been getting worse and worse. And the last few days and bowl movements I've had quite a bit of blood in. I said something to my mom but I don't know if it's really serious or what I should do about it, it happened again today and that's why I'm writingWhat should I do, can IBS lead to Crohns, is there any kind of medicine I can use to make the pain less?Thank you for helpingEDIT:So I looked up some stuff and found that bleeding isn't a symptom of IBS but of IBD hm
