I was diagnosed with hyperthyroidism and am getting better with it and am almost euthyroid. I also had several episodes of panic attacks. My doctor suggested me to go for walks to counteract anxiety. I did so regularly for last 1 month.
I contracted common cold in the start of this week. But I did not ceased to walk. I walk 3 kms. (approx 1.5 miles) daily on a track which has flat surface, staircases and slopes. Today I was feeling a bit low due to the cold, but still went for a walk. As I climbed the staircases, I felt fainted and got a bitter taste in my mouth. I was nauseated and sat down for a while. Heart rate was accelerated and that is ok. But I did not understand that after being able to walk the same track everyday without any problem, what went wrong today?
Was it angina? But there was no pain. A heart attack? Or the old panic attack? Or was it low BP/sugar? I came home, took a glass of water with a pinch of salt & sugar and felt better.
I am 30 years old. Do not smoke or drink. No cholesterol problem, but I am overweight now. Please help me to gauge what went wrong with me?
