There is pain in my left leg from around 1 year. The pain started from below outward side ankle area to outer side calf area to outer side knee. I have gone to many physiotherapist , orthopaedics ,physician in my city. My xray and blood reports are normal except deficiency of Vitamin D which is now resolved. What is the reason of such pain , any idea of pain? The pain sometimes increase or decrease but there is pain. My calf is also very little swollen
