Joint/muscle soreness

El
Does anyone still have sore muscles and joints? 
My knees feel like I've lost the cartilage in them and my pelvic area gets so sore especially if I move around a lot or lift heavy/not so heavy things like the pram or a basket of washing 
The doc said the relaxing hormone doesn't leave breastfeeding mums that quick but I'm 10 weeks postpartum, isn't that enough time for it to go?
