My knees are swelled little bit .I can walk with little pain.I am a lecturer so I need to stand for approximately 5 hours in class and would need to attend classes at different floors. Our college is a 5 storeyed building.I have no BP and no
diabetes. I went on a medical treatment for this knee problem by consulting an orthopedician 6 years earlier.He gave me
calcium tablet and B Complex and suggested me not to sit on the floor frequently.I request for an appropriate medical treatment for this problem.
