I have severe lower abdominal pain . It hurts to sit or walk, touch and go to the bathroom. It starts off mild then gets bad for about six days then goes away. This is the sixth or 7th time but its been 18 mths since the last occurrence. The previous times were more frequent. I m at the end of day 2 of the bad days but felt it start on Saturday. It s not a cramp . It hurts to touch inside and out, from above and below. it hurts all the time but gets worse when I m standing. Like my insides are swollen and something is pressing on my insides. I can t figure if its food related because I hadn t eaten anything unusual. I did just have a 2 month long period but can t remember if I had the previous times.
