Stomach problem since young - Irritable bowel syndrome?

I have had a weak, bad, unstable stomach since i was a kid...
i hardly went to doctors because they were so random.
Recently i went to a doctor who told me i had irritable bowel syndrome, so i already know what it is. I know im not supposed to eat sour, spicy hot stuff, and also coffee, tea. I had medication which was of no use. In the past, i also had a tube go down to my stomach to examine but also nothing was found.
I recently banned myself from drinking milk and eating milk-related stuff such as chocolate and cheese because i find its safer not to eat them, and also oily food/snacks.
I've also banned myself from all kinds of drinks except water, milo and occasionally apple juice.

Nothing seems to work. The pain is still unbearable, unexpectable. its going to drive me crazy after almost a life of dealing with stomach pain almost every week. No particular food triggers the pain.

I wish someone could tell me what to do, because im so stressed out, and i have a hemorrhoid as well

To continue:

I don't really trust doctors anymore cuz none of them really seem to care to have a really sincere feeling about my condition and they just seem to want to do their job and no more. I cant even convey my fear and sadness about my stomach which is hindering me from so many things and making my life so difficult and painful. Ive been to hospital when young many times and i grew to dislike n fear that place. I don't want to keep wasting my parents money and i don't want to keep imposing on people and on my own work anymore but i hate this because i cant control it and its hard for other people to understand how difficult it is to live with this problem, it would not be right to let people pity me all the time either.

This is a great site to help for IBS.

Not only will you find allot of helpful info on here but there is message boards so you can talk to others who are going through the same thing. Also talk to your Gastric. Doc too there are always new things coming out that can help. Good luck I know how hard it can be living with something like this I was told about 10 yrs ago that I have crohn's myself and I had suffered for many years (17 that is) being told I had a nervous stomach and it would pass. Also I have found great relief from it by going to an herbalist too. So you may want to find one yourself I was close to getting a bag for the rest of my life when a friend's mother told me about how much they had help her. Maybe there is a natural way to help I drink special teas in the morning and mid after noon and have found I get only 2-3 flair ups a year (mostly from my own fault of to much fatty like having french fries) but it has really helped me even my doc will suggest to other people that it could help for them with reg visits and there med. Good luck I hope this info can help you. Also I know it is strange to hear when you are having allot of pain try drinking green tea with some honey in it I don't know why but it does help me with my cramps.

Put preperation H on your hemorrhoid to make it go away. Maybe the doctor misdiagnosed you? You might not have to give up all those foods, maybe it is just 1 food in particular that causes you all the trouble.

Are you have diarrhea? Go to GI....sounds like something more is going on. My son has Crohns which is in the same family as IBS. It took over a year to finally get a diagnoses on him. Finally got the referral from the reg. DR. to a pediatric GI. They scoped him through his mouth and bottom took a sample of his ileum(last section of his intestine) That was how he got his diagnoses. He had it really rough and has been through some tough times but he is now doing well on maintenance drugs.

Symptoms before diagnoses of Chrones: Severe stomach cramps after eating, diarrhea, low grade fever....99.9(not high enough to concern a DR. but high enough to make you fell horrible) Weight loss(he stopped eating because of expected pain)

Try taking a teaspoon of RAW HONEY a day. You can buy it in the grocery store. It has natural enzimes and it may help you. If it starts to help ease of and only take as needed.

maybe it has nothing to do with any of this...i know I'm a very nervous person...and anything can set me off...my belly starts to hurt and all the other stuff you talk about...maybe you should go and get a 2nd opinion some where else!!!

Go to a Medical web site, or Google. Crohn's Disease
Good Luck
