I'm a 23 year old female and my left knee has been giving me trouble for the last week. It started while running and has only gotten worse. Walking, twisting, bending and straightening the knee hurts, a lot. I cannot put pressure on it and stairs are a nightmare. I've been icing it, applying a gel and keeping it wrapped and also doing strengthening exercises (these almost always help). However, I've noticed that if I put pressure on my right knee, that hurts too. It's very little in comparison though. I've started taking supplements too. Would you recommend an X-Ray before visiting a physician or to let them take the call?
