Minor constipation symptoms and conditions

My doctor put me on Yasmin about 2 years ago because I had severe menstrual cramps. So bad that I had to take off of school whenever I had my period because the only way to relieve my pain was to lie in bed with a heating pad on max, and i'd still cry over how bad it was. In the beginning of taking Yasmin, I felt awesome, lighter period flow and minor cramps that actually could be relieved with midol but seeing as it was nothing compared to what I had gone through I usually didn't even take that. Now i'm 21 years old, am 15 pounds heavier, I have no energy and severe anxiety and stress. A few months ago I had this 2 week episode with a headache that wouldn't go away with advil, like a normal headache would, stomach pains, nausea and vomiting. I had never felt so awful in my life. I went to a gastroentronologist and was diagnosed with IBS. I always had minor constipation when it wasn't period time and I hadn't been eating good and exercising as usual but this is noticeably worse, and comes with all the goodies of IBS like mucus ew. I'm going to stop taking Yasmin and see if my body starts to work properly again although i'm not looking forward to spending my periods in bed again crying.

About eight to ten years ago i had a violent reaction to lactaid. I had taken it numerous time before with no problems and then I woke up one morning - had a bowl of cereal and a lactaid pill - within the hour I was experiencing severe stomach pain along with vomiting and diarrhea. I thought it might have been due to the fact that i had had very little to eat the day before and only a bowl of cereal that morning with the extra strength pill.

the following weekend i was brave enough to try it again with some ice cream at night (this time i had a full stomach from dinner). BIG mistake - this time it was worse - the stomach pain was out of this world (i have a high pain threshold but this had me in the fetal position) and i couldnt leave the toilet and trash can for a few hours. My girlfriend was scared and called one of those nurse hot lines. they told her to coat my stomach with some kaopectate - which seemed to help. I checked the bottle of lactaid - and the expiration date had passed - so i threw it away and swore off of lactaid pills. fortunately they came out with the lactaid milk!

Fast forward to now - never touched the stuff again. well the other day I was out of lactaid milk and my wife (yes the same girlfriend) had picked up some samples of lactaid pills at a trade show - so I guess with the passage of time - I forgot how painful and miserable the other experiences had been - so i took the pill. Nothing happened!

Last night i decide to take another one because i had a craving for ice cream (had been awhile!). I figured it was ok since i had no reaction a week ago. Well sure enough - within the hour I was on the floor in severe stomach pain - followed by vomiting and diarrhea. This time we had kaopectate in the house - so i started taking it - well i just threw it right back up.

This episode lasted about an hour and a half this time. There was a metallic taste in my mouth about the third time i vomited, and the fifth and final time, there was puddle of yellow liquid that came out at the end.
