Hi there, Thank you for writing to us. I am sorry to hear that you are in pain. The main thing is that there may be an injury to the ligaments of your knee. The best test that is available to definitively rule out any injury to the ligaments or the soft tissue around the knee is MRI scan of the knee. X-rays are usually useless in this regard. Therefore I completely agree with your doctor in saying that MRI is required. Meanwhile you should take over-the-counter anti-inflammatory medications like ibuprofen or naproxen for your pain. I would also like that you should apply a knee brace and give your knee as much rest as possible. To reduce the swelling you can also apply ice after wrapping it in a cloth to the affected area three to four times daily for fifteen minutes each time. Kindest Regards Dr. Zia MD
