I am a 26 year old male with a history of canker sores, chronic stress, headaches, and abdominal pain/cramping. Both sides of my family, according to my parents, have sensitive guts, but no one has an official diagnosis' with the exception of my great uncle who had diverticulitis. Over the last year and half about, I have had 3-4 occasions where I have had severe abdominal pain/cramping (starts in the late afternoon and lasts a few hours) to the point where I start to sweat. The next day my stool will be tarry black, but the day after that it looks normal again. The last time it happened was in January and I finally went to my PCP and they told me about the possibility of an IBD and it scared me a little. I should also mention I have been going to the gym 4-6 days a week for the last 8 years and have taken plenty of supplements over that time including pre-workout. Although, as of now I haven't stepped foot in a gym for almost 2 months now (feeling tired and frustrated with my condition) and haven't had any supplements for about 4 months or so. I weighed about 195 or so 2 months ago and am about 182-184 now ( I don't eat nearly as much as I used too, but I still have an appetite.). I also used to drink 6 cups of milk for a long time to bulk weight but stopped that a year ago. I mention this because I am wondering if this contributed to damaging my gut. 2016 has been a rough one for me medically, I was very ill one day (flu like symptoms) and the next day it went away, I was diagnosed with pityriasis rosea (skin rash lasted 2 months and went away on its own). I have been tired A LOT, even with plenty of sleep. I have also been getting a lot of canker sores over the last couple months, I usually get them a few times a year, but now I get one after the next and it sucks. I experience bloating and cramping that occurs later in the day mostly, but it isn't painful, just uncomfortable most of the time. I have regular stool movements (no diarrhea or constipation and it looks normal color). Every once in a while I will get an abdominal cramp that hurts and the only way to alleviate it is to lay down. Also, my sleep is fine and am never woken up my any issues and I feel just fine every single morning, it is later in the day when my symptoms creep up on me. I have researched many things and am currently on a probiotic, turmeric, and I eat a tablespoon of coconut oil every night. I am also trying my best to avoid foods that are hard to digest, processed, or are bothersome (It is VERY difficult). Last thing I want to mention is this whole thing is causing me anxiety, I am always worried about the next time I will get abdomen pain. If this is a systemic condition, I feel like I am going through a flare up. Anyone have any insight or tips?
