### input:
I had a really bad stomach ache last night with a lot of cramping. I went to the bathroom and just sat there but couldn t go. I started to sweat profusely and when I got up from the toilet I started to feel very dizzy. This has happened before and I usually try to get to a low position incase I faint. Anyway, I was leaning on my ironing board, feeling sweaty, dizzy and started the chills. The next thing I knew I was lying flat on the floor, on my back. My floor is some type of a hard granite so I think I might have given myself a concussion. The back of my head has a huge lump, I have a very bad headache and just feeling very tired. Never mind!! I didn t see that you guys charge for this. I should have realized that.

### output:

Hi. You have two major issues.1. Related to the abdominal pain and sweating, fainting and so.2. Head injury The cause for severe cramps that lead you to the bathroom, profuse sweating, dizziness and falling down must have been died to severe intestinal infection causing the third space loss of body fluids into the intestine with electrolyte imbalances and severe toxemia due to intestinal infection. The head injury due to fall on a granite floor can cause concussion, internal bleeding and so on. The hematoma at the back of the head will resolve soon. I would advise you to report to the ER urgently to get yourself examined for vital of pulse, blood pressure and other signs, and get a CT / MRI scan to prove or disprove the internal brain injury. You will also get intravenous fluids and antibiotics and supportive medicines. Also gets observation for head-injury.
