My 23 yr old son is having symptoms several times a day of a tingling sensation that starts in his sinus area down his neck to his chest then hands. He feels like his heart is beating out of his chest, heart rate has been as high as 140bpm is bounding, and his b/p has been elevated to 160/110. He feels like he can not take a breath in, and becomes shaky and lightheaded. He has had 2 EKGs which were normal, visits to the ER and Urgent Care centers where he is told he most likely has anxiety, and was given Lorazepam 1mg to take for his symptomT. this all comes on very suddenly. At times he is just at home watching a movie, or visiting with friends. He has never had this problem before, and now it has been going on for just over a month. He has works full time but says he is not stressed at his job as a welder/mechanic, he has no insurance at his job, so this is getting expensive with no resolve. Any suggestions?
