Okay. I m 15 years old, kinda overweight but not as in fat,I work out everyday on a crew team. I had 2 seizures during school within two weeks and both days it happened right after I woke up. I was sleeping in a study hall the 1st time and i was sleeping on the crew bus the 2nd time. I went to the hospital both times and they said they couldn t find anything. Ive done many tests like EEG, EKG,and MRI s. I m not epileptic and have no record of seizures in my family. Just today I was found coughing up blood and was sent home. I feel a little bit of chest pain every now and then and get light headed sometimes when i stand up. The 1st time i had the incident I went for a check up and the doctor said i might have POTS (Postural orthostatic tachycardia syndrome) but my blood pressure didn t change as much as it needed for me to have POTS. I didn t eat lunch but I ate a big breakfast. How would I every find out whats wrong with me? Is the anything anywhere that says this has happened before? Also, should i stay home for a while, people keep telling me i should but I m to committed to my school and sport.
