My 27 yr old son has been to the ER twice in the last 2 days with chest pain, lt arm numbness, high blood pressure and dzziness. All of the usual tests were done. All normal, both times. He had the same symptoms about 6-7 yes ago. All tests (EKG's, ECHO's, stress test, etc) all normal. His b/p goes up sometimes. I think that it is stress, but am still concerned that the docs are missing something. What do you think?
