I went to the gym this past monday for the first time in 3 years. I did 10 min bike, stepper 5 min, and pushed/lifted 10 - 20x upper arms exercise about 15 - 20 pounds.
Just yesterday, I felt my left hand as if it feels "heavy," weak, but no tingles, or anything of that nature. But the last couple days I'm having like a "hot" or burning" sensation in my arms more the left one, lasting a sec and then going away.
The, just today, for about half an hour, I felt as though I couldn't catch my breath. I was on the bus heading into the city. This had never happened before, so I just took the next bus home. That feeling went away shortly after and never returned.
But now I do feel a sense of nausea, and those hot sensations on my body...should I be worried?
