Hello. This might seem strange, but I am asking this question for a long-term project. If a young Caucasian male about 31 years old is experiencing moderate-to severe head and stomach pain made much worse from a severe panic attack, what are the possible causes? Vomiting has occurred, due to over-stimulation of light and sound. It lasts about six hours before dulling, but not going away completely. Thank you so much, Melanie
