After I get off the treadmill, I have these sensations in my legs. Its in both legs from my hips all the way down. It just feels like there are pulses going up and down my legs and in all different areas. It doesn't hurt at all, just feels strange. I first thought it was muscle related, but its goes all the way up and down my legs until after my heart rate has lowered. I'm not much of an exercise person, so maybe this happens to everyone. I also do not have any known heart problems. Anyone have similar experience?
