Hi, my name is andie. 1 month ago, I was given 800 ml ibuprofen, I now get sick after every meal. pls help !

I never have had this problem before and the ibuprofen was prescribed for a knee injury. After 3 days, I stopped taking this medicine, however, if that is what messed my stomach up, it will not go away. It is miserable, and now I cannot go out and eat with friends / family without having to make a beeline for home immediately afterward. I am not positive the medicine caused it, but nothing else happened at that time and I have never experienced acid reflux / heartburn before. It feels like I have to vomit real bad, you cannot do any sudden moves because you feel like a time bomb, only you never vomit, you just have 1-2 hrs or more of extreme nasuea. About the only thing I can do is try to go to sleep, when I wake up, it is gone, but I am dreading the next meal. I have never been a milk drinker, not even in elementary school and I just cannot do it now. I have noticed that it doesn't matter what I eat, the end results are the same. What is this and how can I get rid of it ? thx

Best thing is to check with your doctor or ask your pharmacist what it could be. could be any number of things but you need a medical specialist to tell you for sure.
