Hello, I am 12 weeks post delivery of my first baby. Since I was 8 months pregnant, I have had quite bad knee pain. The pain is in mainly in the joint line,worse when trying to sit down /stand up. Night time seems worse than during the day. My weight gain was almost nothing till 6 months of pregnancy and then suddenly 10-14kg up. I still have some kilos up. I have been active person before the child birth and doing a lot of yoga after delivery (no cardio as I do not want to loose milk). I have tried week without exercise and resting as much as possible and week of everyday gentle exercise but there is no difference in my knee pain. Could you please explain why I am getting these pains and what I can do to help? I do not want to take painkillers but sometimes the pain is horrible.
