Hello, today I have been experiencing an extremely mild warm wave on my right leg, around the outside of my calf. It is so very mild that I had to stop to wonder if I really felt something. It happened 3 times throughout the course of today. I am 35, female, active, drink a ton of water and don t sit for prolong periods of time. I am a stay at home mom with a 3 and 2 year old so they do not allow me to sit too long. Is this sensation something to do with a nerve?
