Well for the past month now I have been complaining of back pain and sotmach pain. Went to the doctor, got my blood taken and it said low iron. I was scheduled for a stool sample, but I am constipated on a regular basis and had already gone that morning and the next day I went out of town, I will do the sample when I get back. But since I've been out of town my stomach has been hurting constantly, and my back pain has only gotten worse. I've been talking to my mom and she said this happened when I was 8, but the insurance ran out so we didn't do anything about it. Now, at age 16, it's back and really hurting. After I eat my stomach starts to burn, and this morning urine kept leaking out of me (Sorry TMI). My legs are always falling asleep and I have constant muscle cramps as well. I've been reading up on some symptoms and it said headaches can be one. My whole life I've suffered from severe migraines but no one knew why. Also, I've always suffered from bad mouth ulcers. They went away for a couple years, but the past two weeks i've gotten multiple little ones all around my mouth. Another thing is, about a month ago I had mucus in my stool, I freaked out and didn't tell anyone. I haven't had any mucus lately. I've been getting some joint pains as well, like I can't crouch down for very long without my toes crampng up and things like that. I've really worried because colon cancer runs in my family. Can anyone please share their stories and symptoms?
