Pain after 20month post OP
I am 20months post OP (ACL surgery + meniscus tear + chondroplasty). I did recovery for good 5-6months and then I got pregnant post giving birth I have not done any exercises and now after 9months of birth I started doing excessive walking and physical activities I am feeling extreme pain in my surgical leg with stiffness,and a lot of knocking sound the pain is so intense that I can’t even walk long distances anyone has any recommendations? Will this be solved if I start exercising now or do I need to see a doctor again?
