I am 4 weeks postpartum and I am having pain in my knees and hands still (the same pain I started getting in the third trimester of my pregnancy). My hands are still swollen and I cannot wear my rings. It feels like what I imagine arthritis to feel like. My knees hurt each time I sit or go to stand from sitting or walk up and down stairs. I would of thought this would be gone by now (all the water retention and swelling that is) Any idea why I am still having this and should I be concerned about the pain in my hands and knees? What could it be?
