Hello, I have studied your case. According to your symptoms and findings there is osteoarthritis of your knee. You can start cartilage protecting medication like Chen Chat Doctor. Take analgesic and add tab methylcobalamine 1500mcg daily. Physiotherapy like ultrasound and tens will help, along with knee exercisesLife style changes will help in reducing pain which include, ACTIVITY MODIFICATION -It is important to maintain as much activity and joint motion as possible, but impact activities will aggravate arthritis. Running and jumping will often accelerate cartilage loss from the joint. The key is to focus on low impact activities, such as swimming or cycling.  VISCOSUPPLEMENTATION: Hyaluronic acid injections given into the joint (especially large joints like knee joint) in prescribed dosages will give good short term pain relief in arthritic joints ranging from 1-2 years.
