PP joint pain

Have any of you experienced severe joint pain after giving birth?

I was good for about a month after giving birth. (I gave birth in July so the end of August) Then I started getting sever joint pain mainly in my knees and ankles. If I sit too long in one position I have problems getting up and start walking like an 80 year old. I’m 24. I’m not overweight. I had only gained 22 pounds my pregnancy (only 2 pounds more than my heaviest weight)

After a couple steps my joints (ankles and knees? Loosen up and I can walk just fine.

My hands and wrists get stiff too. But nothing compared to my ankles and knees.

Does anyone have any tips? Trick to help with the pain?
