Hi,
Your working needs lot of standing /walking to which you are not used to.The standing posture brings about stgnation of venous flow. this brings about a condition called Vericosities ,if its unattended. you can add few things in your life style to enhase venous
drainage....
* Start doing exersizes daily for 45 mts. speceially
. walking/leg raising/ cycling in sleeping posture with legs raised &folded in knee/sitting on a chair & trying to draw letters A,B,C....,
*Take pillow under feet when you sleep.
while working ,have a short break try to put your feet on a stool/do the feet work outs as describewd earlier,
* Try to reduce weight. have healthy,balanced diet with creamless milk,pulses,cereals, lot of fresh vegetables & fruits .
* Take vitamins& calcium suppliments.
* all of this along with exersizes for knee joint will help pain in knee also
Some pain killers can be taken, but if you need them, better to cosutlt a physician/orthopedic Dr. for expert advice.
Thank you
