Hello everyone im a 19 year old male about 5 foot 10 im very under weight 107 lbs to be exact which also worries me very much but eat constantly i recently quit smoking about 8 months ago and have started feeling very strange ever since. Ive been experincing these episodes where my whole body shakes and i just cant do anything i become lightheaded and feel extremely hot sometimes these things come without warning while im doing absolutly nothing and I am afraid to go out and do things due to this I also expierence chest pain stomach pain nausea and headaches. The clearing of the throat is there toop the feeling of something back there is present during these episodes and it does not stop ie been to the hospita on multiple occassions for it they have told its GERD and anxiety attacks some episodes i do a little deep breathing and it goes away but some dont i just breathe until they go away but they usually dont they gave me prescriptions for gerd one of which helped and i felt fine for a few weeks but the episodes still come i doubt its gerd i looked up what to do when you hae gerd and have been following the guidelines very strictly down to the last letter ie been drinking nothing but water for years now but i eat the regullar foods oatmeal for breakfast and then either a nice sandwhich for lunch then an apple before dinner and then i wait 2-3 hours to lay down and go to bed. some days this works and somedays i cant stop it and i have no clue what to do about this ive been trying to get into the doctors but i hae no car and unemployed and no insurance so its hard for me to get into the doctors and that is also a problem because when i call 911 the cant run tests on me and i feel like i should sorry for rambling on about this its just im very scarred and am expieriencing an episode now and venting about my problems calms my body usually after an episode i feel very weak and tired oh and the color of the spit i yack up from the back of my throat is clear but does hae the feel of muscus you know slimy and what not. if any of you could give me a little advice on what this may be it would be appricieated because i feel like knowing is half the battle when facing an illness of any kind thank you for reading all this and god bless....
