### input:
Tonight I have severe stomach pain . My stomach feels bloated and hard. I ve had stomach problems since last Tuesday, consisting of nausea , vomiting , and diarrhea . I mostly took Pepto Bismol to deal with it. When it started there wasn t much pain but the pain has gotten terrible. Sunday night I was in such pain I went to a 24 hour CVS where the pharmacist recommended Zantac , it helped and I was able to sleep. However, it doesn t seem to help with the pain anymore. I went to an urgent care facility yesterday since my doctor s office was closed, at first my blood pressure was through the roof--the nurses words--so the doctor gave me IV fluids as well as IV pepcid and zofran as well as a prescription for zofran. This morning I unexpectedly had diarrhea--I was in the shower, felt like I was passing gas but instead a large amount of diarrhea came out. When I was cleaning it up, most was brown, but a small amount was red. Between the pain and the possibility of blood in my stools, I m wondering if I should go to the ER tonight. I have an appt with my Dr. tomorrow but the pain is really bad right now and I m wondering if I ll be able to sleep. Thank you for your advice.Edit:  Went to ER, then to my regular Dr next day.  I have gastritis, and Im on 2 different antibiotics now.  Starting to feel a little better.  Cant eat anything but toast and gatorade though, so I miss real food.

### output:

There are chances of stomach infection as you have gastritis and acidity you only took antacids if your antibiotics are working u can continue with antacids liquid antispasmodic SOS for pain lot of warm water non greedy non-oily non-fatty food for few days the infection can also cause blood in stool if the infections are over you can get relief but you must consult doctor to find the condition physically and treat accordingly
