Ughhh my knee again.please helpp?

due to the severe pain u tore ur ligament, the only way to get it fixed is through surgery unfortunately. knee ligaments dont regenerate by themselves unlike other ligaments. im guessing its swelling more cuz ur trying to walk on it which is a dumb idea. ice it, it will shorten the recovery period and swelling is not necesseraly bad, it indicates something is wrong but its not bad, ur body uses it to avoid u moving your injured area and causing more damaged. Gotta go get an mri and if its a tear surgery for sure
