For the last few months I have been having the following symptoms which occur stronger and more frequently when on my monthly cycle: excessive bloating, some gas, pain in lower left side that is more a constant dull pain, queeziness, food seems to go right through me (bowel movements several times a day with a lot of cramps). I am an excessive Diet Coke drinker and have been under more stress than usual this year. When I explained my symptoms to my "so called" doctor, he said it could be IBS but made no suggestions as to what changes I could make or medicine to take. I would appreciate any help any one can give to me. Thanks!
