Hi all, i am 28 years old, about month ago i had my first panic/anxiety attack or what they say it is. Simpthoms: Dry mouth, body like having seasure, feeling like getting uncoutiouse based on lack of rapid breathing, head like on fire/ or like in airplain that crushes. That day my blood presure is 150, h/r don't remember but fast...i never had problems with my health over all. And yes i am typical coffee drinker, and social cigarete smoker(no drugs). I have no insurance and currently looking for a job, but I went to ER, they checked my blood, vitals, chest xray, EKG <-heart, and erine test. ALL SHOWS IN PERFECT CONDITION BY ALL MEANS. When they asked me how i feel during my event, i startd my 1 or 2 ears were getting tempature hot like i felt that it's not notmal, they checked ears, no ear infection. Over all docrots in ER couldn't find anything, and i told them that before even i feel like my brain is hurting literally where i can't controll it, like someone puts niddles in my brains and it starts...
I went to psyciaatrist and was on CELEXA for 5 days, i hated and wasn't myself and still had couple events after all. Now i am taking 5mlg of LEXAPRO and it seem helps a bit, but i get brain sharp pain and my hands are always wet/sweated during day and then i have to take a deep breath and kinda try to breath it out. I am not sure what to do, but i feel scared and no one seems to pay attention or when i talk about everyone tells me don't worry about it. i know i am not exadurating about my pains and discomforts, but i don't know what to do. I want to do the CT scan but with no insurance nobody cares seens now it's only the business rather then help for people.
Please advise me something i don't know, or how to get checked up my brain in particulary. Thanks to all that responde regardless, and sorry for gramar mistakes.
