Patient: Hello, I am a 19 year old female who is suffering with knee pain, on my right knee. It hurts when I sit down too long, go up and down the stairs, hurts when I touch it, lay on it and so on. It’s been like this for a for years now. I fell a few years ago but no sure if it’s related. It’s hard to walk and I have two children so I’m unable to run about with them. I can bend my knee it’s just painful and uncomfortable! Please help, thank you!
