Hi loangoddess !
What you describe is totally normal, don't care about it it's as you have guessed a side-effect of your energetic training. It happened to me on feet and hands about 2 weeks after i started daily NEW training (more than 2 years ago now)and disapeared rather quickly (in 1 week). It never came back. The trick is to continue your training sessions and it will go even faster. It seems to be a physical consequence of the heavy developement of the tiny exchange ports on soles and palms. So it's a good indicator of your development
