Hi 3 weeks ago I pulled a table into my knee and it felt like I hit a nerve severe pain after for one week and it started to feel better,then one day I tried to run to get across the highway and I felt A pull behind my knee And a sharp pain and I almost went down.So I ended up at a clinic I was told no need to do an x-ray because if the knee was fractured or broken I would not be able to.walk or stand,I then said alright your the professional.A was sent home with a paper on treatments for sprains and ibuprofen,now I am in pain and my knee hurts in the back and my leg gets stuff and it hurts at nighttime and also I is painful going.up.and down stairs.My question.should.I go to the hospital instead of returning to the clinic?
