I had same issue and I was not able to move my lower body at all at night time when I used to lay down in bed... and I used to be like wooden log for atleast 15 mins ..... then after all the pain i used to sleep on my back and had to lift my entire lower back towards ceiling of the room 2 3 times and then I was able to atleadt move that too with pain... but surprisingly when I joined office when my lo was 6 months old my thus pain had vanished.... now I don't have this issue at all at 11 months... what I concluded is it was coz I used to lift my baby in wrong posture and use to have long sitting hours for feeding

hi Bhargavi, have U tried some thing to get rid of this problem? any thing worked out?

same thing is happening to me also m 8 n half months postpartum

Two things which are needed - a check up by an orthopaedic so that the right diagnosis and exercises can be prescribed. Following which you will need to meet a physiotherapist or a pregnancy exercise specialist to help with the same. Additionally you may also need D3 and B12 and again this needs to first be checked before you start.
