Hello and welcome to HCM
I am a General Physician and read your mail in detail. As per your mail you get relief by taking shower so their are more chances that your problem is related to heart issue like AF (Atrial fibrillation
) or PSVT
Do your EKG at the time of episode or consult your cardiologist. If needed go for holter examination. Holter is a 24 hours record of heart beats in EKG pattern. With this we get to know what happens to the rate of heart during episode.
The frequency of the episode are very frequent so you need to get treatment as early as possible.
Consult your cardiologist near you and get your treatment started.
