You might want to watch the oatmeal. I have had the pinching in the sides, on both sides, high and low, for most of my life. I finally got really tired of it and started questioning my drs. About a year ago. I wanted to make sure there was nothing wrong with me. So much that I had been told through out my life in way of pain had ended up as being major, (Heart area pain ended up being large hole in my heart, being found after stroke at age 40). So I started the quest and didn't let the Drs. say relax. I finally had a colonoscopy to find I had kinks in my colon, and really needed to stop all fiber, and drink the Mi_____x once a day because of how kinked up I was. He was shocked because it was so difficult to do the colonoscopy. My pain was from not emptying properly. I thought I was, but guess I wasn't. Now I don't do it like I'm told to. And the other day, I forgot and for two days ate oatmeal. I ended up writhing in pain on the floor of Hobby Lobby. The pain didn't subside for 10-15 min. My husband, an EMT was so worried, but I had realized what I had done. I went home and started a double dose, for 2 days, and then single dose for 2. I thinks I'll try 1/2 dose every day. It really helps. But do get checked out to make sure it is the problem. And people, take care of yourselves!
