I have had a problem with clearing my throat for a couple years now and I get bronchitis every time I'm sick. I am a 5'11 girl and I only weigh 105 lbs because of my appetite loss. I go days without eating and when I eat something small, like HALF a taco I feel like throwing up. This has been going on for a little over a year. My stomach always hurts, ALWAYS not a single minute does it feel ok. I get heartburn a lot and I have the hiccups 24/7 even if I don't eat or drink anything. I always have trapped air in my chest and its very uncomfortable and comes for long periods of time almost right after eachother. The hair on my arms and legs aren't really growing. I get random bruises everywhere sometimes about 20 right next to eachother. I CAN NEVER SWALLOW. EVER EVER EVER. This difficullty has also not gone away in about a year. The other day the roof of my moth felt like it was on fire and the one time I got hungry I couldn't eat. I feel like I have to shit every five minutes and the feelings last for 2 -3 mins at a time. I have had diharrea for almost a year. Last week I started noticing blood in my stool, not a little a lot. The entire thing is BRIGHT pinkish red. Today it started being pitch black. What is wrong with me? I'm only 15 but I have been addicted to nicotine for a few years so I'm thinking I might have something wrong with my esophagus and my stomach. Please help. Thank you,
