Hello. My friend is experiencing some abdominal pain, and I wanted to get some help to figure out what it might be. He is a 15 year old male. He said that he is having pain, in his mid abdomen, near his navel, and pain to the lower right of his navel. He gets more pain when he walks around, or moves suddenly. He has not many other symptoms opposed to that. The pain has been continuing since Saturday morning (it is Sunday afternoon right now.), and it has been progressively getting worse over that time. He pressed down on the area where he is experiencing pain, and it is a bit firmer in that area. He was recently taking Dimetapp, for a cold, from the Monday to Friday before he began to experience pain. He takes 10mg of melatonin each night to help him sleep. He went to the washroom, and there was no blood in his urine, or stool. He has no allergies to anything that he is aware of. This has never happened before to him. He ate a bit of granola earlier this morning, but had a loss of appetite, so he did not consume much. He also feels a bit nauseous. If you have any more questions, or any idea of what this might be. You can email me back at YYYY@YYYY and I will reply back as soon as I can. Thank you for your time.
