I sometimes have spasm issues right where you are describing. My cramping spasms are debilitating and relief is not felt until the wave of cramping is over. It only lasts a minute or two. I have noticed the spasm occurs when I have pressure on my colon or stomach area, such as coughing or when constipated. I am searching endlessly for answers and figure it all has to do with diet and eating. I think I may have found a good book to start with, named Eating Alive, written by Dr. Jonn Matsen, ND. It is an easy read all about digestion with illustrations. I recommend it to anyone with a stomach. Good luck to you all.
. I have no ideas because I get it too. EXACTLY. They can't find out. Stress they say.
Sorry but maybe somebody can help us. Anyway at least we're not alone. There's two of us!
