Well… not seeking medical / professional advice and/or a diagnosis is almost always a bad idea even if just for peace of mind.
Without a proper diagnosis coming up with treatment/management/rehab is foolish at best but since it’s not too serious you don’t need any of that anyway.
If it’s nothing srs then a month or two out is excessive. Avoid movements that aggravate pain while continuing movements that you are able to do until your symptoms subside and return gradually to full activity. Won’t lose much strength or ROM in a few weeks especially if you continue to lift as able.
Sounds unlikely that you’d have anything too srs going on. Still.
People do their ACL all the time with jumping twisting mechanism. I think there was one time a footballer was celebrating a goal too hard and injured himself lel. Pop and then since the ACL itself has no pain receptors it can be mostly painless and you can walk fine.
Other ligamentous injuries could be MCL or LCL or it could be related to the cartilage of the knee which could put you at risk of further degenerative joint disease down the line.
If it is more serious pls go see someone qualified to tell you it’s “not bad enough to require surgery” and go from there.
