Hi, I've been practicing ninjutsu for two years and I've been getting quite proficient at it, but I have a problem that I only recently revealed to my sensei. I have a heart condition, or a lung condition (can't tell exactly) that can best be described as arrythmia. I went to the cardiologist and they said that my heart is perfectly healthy, not a murmer or affliction in sight. I told my sempai about this on Monday during training, as it was so bad that I was forced to sit out, and he said that it might not be arrythmia, but a condition with my lungs. So, my question to you guys is this: Is there any way I can traditionally heal this affliction, short of going to the doctor and getting drugs or a surgery?
