Good morning everybody...I just need some advice please. I was diagnosed with fibromyalgia last year. beginning of the year my sister passed and I was under alot of stress. sitting everyday for a week at hospital next to her bedside I hardly ate. I felt some spasm in my colon. a week ago i had severe pain on my left side (abdomen) I had oneday abit of diarhee...then after 3 days i could go to the toilet. I saw my gp but because I've got a history of ovarian cyst he sent me to my gynea...well gynea did a scan and thank God no cyst but colon was blocked. He prescribed me 2 x 135ml Lenolax which cleansed it. After a week i still get on and off pain but I go to the toilet regulary now. Can this be IBS (irrited bowl syndrome) how long does it normally last? I'm so tired of pain. This morning I got up very moody as my left side was paining but after I started to walk and move around the pain subsided.
