Yes po, but may technique po para hindi mag cramps, exercise muna yung legs niyo, always elevate it to have a better blood flow circulation, I put socks during bedtime, always sleep on the left side, water din dapat. At wag istretch agad ang paa kapag nakahiga dahan2 lang sa stretching. For the numbness naman, avoid na masisikip na footwear, always elevate your feet kahit naka upo.
salamat mie
