I'm 13 & I've had severe stomach problems for over a year now. I've gotten numerous amounts of tests done, & I'm always getting the same answers, "We can't find anything." I have these sharp pains all over my stomach, it feels like I'm being stabbed over & over again, the pain never goes away. Also, I get what I call "episodes" & the pain is unbareable, & the pain on a scale on 1-10 is beyond 10, & I scream because I'm in so much pain. I'm always feeling sick, & barely keep any food down. I get very irritable & tired. I do sometimes cough up & throw up blood. I also get night sweats & chills, & have lower back pain. I have had a siezure during this all. I'm on a search to find what's wrong with me. I'm only 13, & I'm so stressed out & this has changed my life completely. I am starting to loose some of my hair, but I don't know if that is caused by the stress or this problem. Having pain every single day is not the best feeling. Please, if you have any opinions or thoughts on this please share them. I just want to know what's wrong with me. Please help.
