Hi, dd is 4.5 months old, since her birth I have had really stiff & sore ankles, feet and knees. I thought it was some post birth thing but it hasn't really cleared up. I am more sore in the morning - find it really hard to walk down stairs before I have had a hot bath. Anyone else had symtoms like this? Am going to see doctor next week but would like some information. Dreading being told I have arthritis
