Question: Just a little history, I am 47 and after suffering from constipation for most of my life at about 28 it switch more to diarrhea, It seemed I was bothered most by painful cramps and diarrhea during that time of the month or when I was under a great amount of stress. Doctors have called it spastic colon and IBS, but no one did tests. Over a year ago I had a very serious episode that included bloody diarrhea that lasted 2 days, but I had very loose stools for two weeks after. My doctor said food poisoning or diverticulitis. (I think it was food poisoning). She order a colonoscopy in 6 weeks but by then I was OK and canceled. The pattern went back to having the normal painful diarrhea (no blood) at the expected times. OK, so last week my mom had a stroke. I immediately got an episode of painful diarrhea that lasted about an hour. Afterward, for a few days it varied from normal to ribbony to watery. After that the colon area stayed what I would describe as sore for several days after. When I would take steps to walk or sit down it hurt. That got better but now I am having little sharp spasms in the colon area about every minute or so. This has gone on for two days. I am a produce farmer and am trying to plant but it seems to aggravate the spasms when I squat and bend over. I have to bend over planting for several hours a day. So I have 2 questons:
Does this sound like IBS? and When I am bending over to plant for long peroids am I actually aggravating my colon and preventing it from getting back to normal. Do you think I am actually causing the spasms by this action? And if so, could I actually aggravate it enough to throw myself into a terrible attack like I had a couple of years ago? The last thing I need is to put myself out of commission for two weeks. It's not like I have a choice whether or not to get my work done, if I did I would rest and see what happens. I have a lot of hours of bending at my waist ahead of me. I would just like to know if I am pressing my luck with all this bending over or if that is hopefully irrelevant to the situation. (I have no other illness and take no meds)

Just to clarify the blood was only once over a year ago, and may have been food poisoning as I had eaten Chinese that did not taste right. Doc said either food poisoning or diverticulis. Now I am having the normal stress related symptoms I have always had, except for the spasms. I know I need tests. But for now my question was really about the bending. Will squatting and bending at the waist for an extended period aggravate the colon if it is already messed up from stress. My problems are ALWAYS stress related. I have to bend to do my job, but I am wondering if I am prolonging my problem with the spasms by bending, or if that has nothing to do with it. Thanks!
