About a month ago I fell of my moped and landed on my knee it was hurting till about 30 mins after the pain reduced a lot but the next day it was worse over time it got better and better but it seems to have plateaud and is not really healing anymore there's still pain when I can bend my knee but when it gets to a point almost close to fully bent I still get pain and if I straighten it out not as much as when I bend it but still pain I'm looking to do some physical activities should I hold off?
