I have knee medial knee pain. Movement to is not restricted. If I use my fingers to try to find where it is tender I find nothing when my leg is extended when bent and I feel the centre of my knee on the inside it feels tender. I cannot be specific when the injury occurred it seemed to come on gradually. I played tennis on Tuesday. All ok. Then Friday a one hour coaching session all ok. Saturday morning a little stiff but no pain. Played 2 hours Saturday morning. Sunday morning a little stiff slight pain. Stiffness went, but if I moved quickly I got pain. I was playing a tournament. Sunday evening stiffness and pain but not severe but two sharp twinges. Today about the same and a couple of sharp twinges. I have for a few years been unable to use a stationary exercise bike because I quickly get the same pain that stops as soon as I stop pedalling. I do not get the pain riding a road bike or running. There is no swelling or heat. Any ideas?

Hi, Thanks for your query. Your pain is due to Arthritis. When bone is not able to take weight due to arthritis than it has to be shared by muscles. It causes pain in thigh and calf muscles.Also, some time it can be due to nerve compression. You can judge your self. If your pain increases on walking and relieved with rest, it is suggestive of nerve related pain. Arthritis pain is present even when you are taking rest. I will suggest you following. Hot water fomentation. Volition ointment Tablet Pregabalin M one daily at nighttime. Calcium and vitamin D3 daily. Tablet Tramadol one daily. Please consult your doctor before taking those medicines. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
