I went home Friday afternoon from work throwing up, body aches, maybe a slight fever. Saturday still couldnt eat, tried broth and crackers late last night, threw up again. My stomach feels full and I am having horrible cramping. Just realized that I havent pooped since Thursday. I dont understand what is going on.
As per your symptoms details you are suffering from Acute gastritis. This can be due to some infections in your stomach due to intake of contaminated food materials. Symptomatically you should take over the counter some anti-acid and antiemetic Chat Doctor.  But you should undergo Upper GI endoscopy and one ultrasound abdomen to confirm the diagnosis of Acute gastritis and rule out acute cholecystitis (Inflammation of gall bladder due to stones in gall bladder). For this you meet some nearby physician
