my son who is 18, weighs about 135 and is 6ft 3in started with dirahea the night before last, that subsided, and a few hours later he started with bad stomach pains, saying its like a cross between burning and stabhing. This has been going on since yesterday afternoon, and is still continuing. He has had his appendix removed almost 4 years ago. I m looking for a way to releive some of his pain.
