Itch... Itch... Go Away

I am back! I survived and I feel better for running... I am back on the wagon. My pace was horrible but now I have something to improve upon. I wish I could remember that though I hate running, it does good things for me like increase my endorphins and apparently open my capillaries and arteries... All of which are good things...

I say apparently because I just researched and found that last tidbit. See, when I stop running for any period of time and then start again, my legs itch... It is not painful, just uncomfortable. I never knew why but after feeling the tingle today I decided to look it up... Here is the answer and it creeps me out enough to keep running!

Why do my legs itch when I run?

A. Don't worry; you aren't alone on this problem. It usually occurs during exercise performed after a long period of inactivity. The itching is not on the skin, it is inside the skin.
You see, there are millions of tiny capillaries and arteries inside our muscles which expand rapidly due to the demand for more blood that is brought on by exercise. When our bodies are sufficiently fit, these capillaries remain open allowing maximum blood passage, but, when unfit and inactive, they tend to collapse, allowing only minimal blood passage (which is sufficient for a sedentary person, however). The rapid expansion of these vessels causes adjacent nerves to send impulses back to the brain which are interpreted as an itch.The problem should go away once you have increased your fitness level.


I am determined to decrease the itch. I do not want to be considered a "sedentary person"... Ewww... I just chringed at the thought.

Thank you for the useful knowledge. I also always wondered. I always just thought it meant I had done a good workout. Uh...not true I guess.

That's funny! I always tried to explain this sensation to Erin and she never understood it. I guess she is more fit than I am. Miss you, friend! Keep running!
