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.

Hello, As you had mentioned that you had two episodes on seizures, you need to be careful in future while traveling. Kindly get yourself evaluated by a cardiologist because valvular heart disease can give rise to seizure, tachycardia, blood in the cough. Normal ECG does not rule out any heart disease. You should be taking anti-epileptic to prevent a further episode of seizure. Also, check for your hemoglobin levels. High hemoglobin levels can also give rise to seizures. Please more water. Avoid deny Chat Doctor.  Regarding staying at home, you can carry your routine activities but avoiding traveling or staying alone since you already had two episodes of seizures. Better to be safe and careful. Hope I have answered your query. Let me know if I can assist you further.
