Suggest Treatment For Clicking In Legs While Walking

I didnt have any trauma but was reffing soccer last weekend. I felt clicking when I was walking to the dressing room. I reffed the second half without incident but again noticed it after the game and it has been consistently happening since. The repetitive repetitive clicking feels like it is at the medial aspect of the patellar tendon while walking. It is painless in nature. I can walk a number of steps without any clicking and then it will click, then I can walk another number of steps before it clicks again.
