Hey. Thanks for writing on HCM. You told the symptoms you had. But can you tell me what is your age? Are you a patient of hypertension
This can occur with a few conditions. One is dehydration
. If you live in a tropical country then the heat wave could hit you. Another could be hypoglycemia
. Or a hypertensive episode. If you had less water intake that day then be careful to keep yourself hydrated. Would be better if you rested for a couple of days.
