My son for 9 months has been having these symptoms off and on. Thursday stomach burning. Saturday sick to his stomach, diarrhea and weird feeling. Felt better. Sunday didn't eat stomach on fire, diarrhea, stomach hurting, throat closing and tremors.( jerking motions). Felt paralyzed and hyperventilating. This has happened twice in a week which is more often than before. Has had so many tests and still hasn't found anything wrong. He has the symptoms for 4 days before the major attack and sometimes in his sleep he is clammy and his wife checks to see if he is breathing and ends up waking him. He has laid in bed feeling paralyzed at times not being able to talk or move. It is over whelming and he is so warn out he can barely function. He went to work for 8 hrs one day last week and couldn't remember anything and had to call his work to see if he paid claims and how many. he paid 75 he didn't remember paying. He is not remembering and is very upset over the more this happens. Doctors can't seem to figure it out.
