### input:
Right under my knee it started to swell and it hurts. I put a menthol patch on it and I am trying not to walk on it. I feel some tingling from under my knee to my foot. I covered my leg because it started to feel cold and when I usually do this it helps. I never notice my leg to be like this. I am trying to do anything that I can to relieve my knee. My sisters said I should exercise, but I really don t think this is the key answer to my knee. At one time that I could remember is I walking down the steps and I trip and I stumbled on my knee really hard. After this I started to have this problem with my knee. What can I do to relieve the pain that I am in. How can I help the swelling go down at home or do I need to a Dr.

Hi, thank-you for providing the brief history of you. A thorough neuromuscular assessment is advised. As you have pain and tingling from the knee to the foot, it could be related to a nerve pinch in the spine. As the tingling sensation is a comment feature of the nerve impingement. Also, for swelling of your knee, you need to apply icing to reduce the swelling. Understanding that the knee joint has a bunch of ligaments and any pathology of it may lead to swollen knees. Undergoing a thorough musculoskeletal assessment and an MRI scan will assist in understanding the soft tissues. If the clinical assessment comes closer to the neuropathic pain more, than an MRI of the lumbar spine will be advised to see the nerve impingement. Usually by clinical assessment it can be confirmed and an MRI of lumbar spine may not be advised. Undergoing physical therapy like - Therapeutic ultrasound therapy and TENS therapy the pain and swelling will be reduced. Post which exercises will be taught to strengthen the muscles and in about 2-3 weeks of time you will be fine. Also, to understand that you can perform this exercises at home taught to you by a physical therapist as it will maintain the long term care of the symptoms. In my clinical practice I advise patients to undergo physical therapy and 99% recovery is achieved. RegardsJay In Chat Doctor.
