Stop massaging the joint and weight-bearing on that particular leg. MRI is a preferable scan to see knee joint pathology, specially ligamenta and meniscal tears if any and which may be treated by medications, physiotherapy or arthroscopy in most of the cases. Depending on the type of injury and extent of injury, knee joint takes time from 3 to 6 weeks to improve, and it generally takes months to regain the full strength. </s>
