i know exactly what you are talking about,and if you are like me you dont want to take medicine for everything.the simple solution is water people...the itching usually occurs in the lower body parts because of lack of circulation.your pores in your legs usually dont get sufficient oxygen supply.most people dont drink was much water when they stopped excerising,hence why its extreme at first.your pores are dirty from lack of drinking water.i tested this by taking a two month break but made sure i was drinking lots of water during this time off period,and when i started working out again i had no itch in my thighs,calves and butt area.
