Hi. Yes it might be due to the sports activity which you started and there might be some unnoticed injury. Please try to rest your knee for couple of weeks don't play and take appropriate medication. If still pain persists then we will investigate further. I think this should resolve with rest.

• Contrast Fomentation (Hot and Cold). • Avoid Squatting- • Avoid sitting Cross legged • Contrast bath---It is a form of treatment in which knee is applied warm water followed by the immediate application of the knee with ice water. This procedure is repeated several times, alternating hot and cold. Note that the treatment should always end in the ice water, as heat will induce the body's inflammatory response, while cold helps to decrease inflammation.
