Horrible pain in my small intestine..

I have an awful pain in my small intestine and stomach everyday when I wake up and 10 minutes after every meal. I feel like everything that I eat is being digested in a matter of 5 minutes and when the food reaches my small intestine there is a sort of relaxation but 3 minutes after I have a feeling of strong acidity and pressure. Pressure build up all the time there, at least 8 times a day and that's what really MAKES me eat, cause to be honest with what I feel I have no pleasure eating even though I continue doing it because I know it would be really bad for my stomach and small intestine... It all started in my stomach, the acidity, 5 years ago. I went to gastroenterologist a couple months ago and he told me I had Giardia Lamblia which is an intestinal parasite. He gave me medication for it and said it would instantly go awat and the pain I feel and acidity would remove. He is completely wrong let me tell you, please help :( :( ive been like this almost 2 years now...

I was diagosed with have giardia by a compute program biomeridian.com its fda approven i belive I have giardia but last time I went in I was told I dont have it anymore but I still have symptoms from it. Maybe it just takes forever to go away. Giardia is nasty and makes lower and upper stomach pain and its constant for me

I wonder the same thing sometimes, why is the pain still there when the doctor says it shouldn't, all im really scared of is that the giardia somehow caused a malabsorbtion syndrome preventing my intestine from absorbing the nutrients and food which is what I feel and see from my weight... anyways, please reply anyone
