I get stomach cramps monthly once. During this period I get severe ache below ribs on both sides. I used to pass motion couple of times and the pain lasts for 7 to 8 hours. I went to a doctor and he gave "buscopan". It gave relief but it keeps on coming. I started to see the food pattern why it's re appearing. I found out "peanuts" in some form a day before causes this. I did not have peanut allergy anytime. Why does this happen suddenly? Is there a remedy for this. I know I can avoid peanuts, but is there any remedy for this.
