I have had it. Very painful. Screaming painful. I was driving home when I was experiencing the horrible pain. I was all alone and driving on back roads. Opened my son roof so that I wouldn’t pass out. I must have scared everyone between Denham Springs and St. Amant. Was trying to find a cop to help me. Non around. Imagine that. I took spasm pills that dissolved under my tongue, more than I should have, but got some relief. The spasm pills have been my life saver. I also have Crohn’s. My entire digestive system is always in raging spasms. I also have muscle cramps daily in every inch of my body.
