Knee and ankle pain

[Same1977]

I had a baby 9 months ago and since the birth my knees and ankles are really sore.Not throughout the day but after waking up.Every morning I literally walk down step at the time as it hurts ( debdroom on the 3rd floor ).By the time I have reached the living room on the 1st floor I am fine and the pain is gone.
Just bizarre.Has anyone had this?

That is odd. Did you have any back pain during or after pregnancy? Could be funky nerves, or even circulation problem.
