hi everyone..M 23 weeks pregnant. from last few days M having pain in my lower back n thighs n legs. sometimes it's on right side or sometimes on left side but once it starts at a side it remains for 7-8 days. from last three days it's on right side of lower back( hips k upar) thighs n legs.specially thighs paining really bad..if M walking or standing in kitchen I hav to stop for sometime.in night pain became worse..while in sleep if I wanna move or turn it's really difficult.. 3-4 times unknowingly I screamed coz of pain like thighs will get locked. my gynaecologist has given me a evion LC tab for vitamin E but still M going through this.i want know is there anything serious?? why it's happening? what to do to deal with this pain?
