Hypothyroidism or something else?
Approximately 2 years ago I woke from a sound sleep with my heart racing. My vision was blurry, and I had difficulty walking. I was in the hospital for 2 days and had a complete cardiac workup and nothing abnormal was found. During this time my feet began to tingle. I was referred to a cardiologist. I wore a monitor for 4 weeks. Again, no abnormalities. I started having "spells" when my BP would be elevated. I would get nauseous and have a dry mouth and heart palpitations. Many times, this occurred at night after I had been asleep for around an hour. Occasionally it happened during the day. Went back to my GP. He said my thyroid had been getting sluggish and started me on Synthroid. 50 Mg at first and then increased to 75. This did seem to help. However, I continue to have these "spells" I have a watch that measure ECG. During one episode I took a reading and sent to my GP. He said I was experiencing Afib. Sent me back to cardiologist. I wore a monitor again for 4 weeks. Cardiologist said it was not an Afib reading. No abnormalities found from the monitor. Last night I had another "spell", Heart rate not as fast as before, but very nauseas. I managed to get through the day at work but feel wiped out and have gritty feeling in eyes. Still having foot swelling. Are these symptoms thyroid related?
