6 months after giving birth

Okay so looking for anyone who has had these symptoms after giving birth, I am so sick of being in pain constantly! I have been having a bad bad chest pain that comes so quickly and sharp it happens every so often. Then daily basis, I wake up and I have very very bad achy joints and muscles, I have had cramp/ tightening pain in one of my legs for 5 days now. I have been to the docs had bloods and they did find my liver enzymes were elevated but had them retaken and all fine. Am so sick of feeling so crap
