Swollen Knee and Leg: Causes, Symptoms & When to See a Doctor

Question
Iam having a problem with my knee and my right leg also are swelling  and Iam having problem of bending my right leg, Please Can some tell me what is wrong with me?

Answer
Hi Rose,
From that much information, it is hard to know what is wrong. Do you have any underlying medical problems; recent surgery, recent immobility; any trauma to that area or any sort of infection from a puncture wound or cut? Any redness or excess heat coming from the area? Have you had this problem for a long time or was it a sudden appearance. Has it ever happened before? I will need to know a bit more about this problem before I can hazzard a guess.
