Thank you very much for your reply. i will certainly get back to the doctor about the same.
You should call the doctor who prescribed this stuff to you and make sure you actually got the correct medicine from the pharmacy. Remicaid, for example, is used to counteract inflammation of the bowel and many other parts of the body. That's just an example, in that could be the gastro doc prescribed you one thing, but the pharmacy misread his handwriting or something. So, call the doc who you went to see, and ask him about the drug he prescribed.
It does sound like you may be constipated, that would create gas and make you throw up, which were part of your original symptoms. Go to the drugstore and buy a laxative medicine, like Senokot is a mild, natural means of getting the bowels to move. Also, drink lots of extra water, eat enough fiber foods, continue to exercise even tho you feel awful, like taking a short walk, and eat yogurt. Once your digestion gets back on track, hopefully your symptoms will stop.
