I am been under harmonal imbalance therapy from one month. I am using birth control pills adviced by my gynaecologist. But recently I observe siatic nerve problems like numbness in left leg and little pain in middle of my thigh when I walk more . Please suggest me is this side effect of birth control Pills . My doctor told like it's calcium defeciency but I never experienced these problems before. I am worried Shoudl I stop medication or it's not related to that
