Hello, i’m new here so it’s regarding my knee.

I feel a tear in both of my knees today and this has been going on and off for at least 3 weeks. sometimes it goes away for one week and randomly comes back. I do work although. So my knee feels the tear when i bend it. If i lay down and rest, it decreases the pain. I do put ice on it often but not much as needed. Plz help, I would like to know if anyone is experiencing what im going thru and any advice?
