I m a 33 year old male, I started with a headache which came in cycles, would be very painful, then go away after a very short time. After that, my headache all of the sudden disappeared; however, immediately to follow I had a very irregular pulse which caused me to have a low blood pressure and make me feel a little dizzy and lightheaded and weak. After an evening with this, I went to bed, slept the night, but still had the same symptoms the next morning. Only a short time later in the morning, the irregularity stopped, my blood pressure stabilized, and I no longer felt dizzy, lightheaded or weak. Any thoughts?
