LCL strain and effusion on my left knee

[Red_DragonBones]

This is the result of my X-Ray I had.

LCL strain and (some kind of) effusion on my knee... can the injury be fully recovered? Permanent? I hope not.

I know you guys aren't doctors... still anyway cheap way to treat it? My doc recommended that I iced it and tensor wrap it and put less stress on it... I've done that for a couple of months.

When I stopped icing it though the pain came back... and the tensor wrap isn't as effective any more (how often should I replace it?). Thanks.
