i don't have any ideas, but i have hypertension and have been treated for it about 5 years now with meds. i get the same symptoms, except the passing out one. i also can get panic attacks, infrequently when under extreme stress which doesn't help the hypertension. there is really no solution for me. the symptoms can be a sign of the hypertension and the meds. good luck, i empathize with him. (I also developed Raynauds' Syndrom from a blood pressure pill i used to take).
