How can i engineer my knee, calf and ankle stop hurting?

The ligaments that hold the knee from moving absurd may be "loose" sometimes by immobilizing his knees for a few weeks can help. Also, he may hold tear of some sort, but the lone way of knowing explicitly by having an MRI scan. Try keeping it elevated and keeping rime on it and also - sometimes taking an anti-inflammatory can help,,,,, at hand is aleve and advil over the counter. Try that for about a week and but for better, then he should see an orthopaedic surgeon.
