Hello I am a 17 year old female, weight 144 pounds. 6 days ago a dog ran into and headbutted the inside of my right knee, which knocked me over. I felt considerable pain and my knee went completely numb, so I iced it and carried on as normal as the pain then subsided. I woke up the next day and my knee was very bruised and swollen, I had pain walking and when I did I couldnt place full weight on my knee. Touching my kneecap is very painful and has gradually gotten worse, the bruising is getting worse and now when I am non-weight bearing and extend my leg, I feel a painful and very audible popping inside and towards the top of my kneecap. Taking pain relief doesn't help. Should I got to my local doctor's surgery?
