For 4 days i have been having severe abdominal pains. They feel as if they start in my sides around my kidneys and the pain is sharp and stabbing . It also radiates a burning sensation through out my entire abdomen . The pains seem to come in waves about every 2-3. hours and last for 5-10 minutes. Each pain last 30-45 seconds and has 15-30 seconds between each pain. at first i thought it was really bad gas.
