Under the skin indicates to me that you are talking about a Baker's Cyst on the back side of your knee. They are caused by over use. The bursa is the cushioning between the ligaments and it has been overworked and a cyst has developed there as a result. It will never go away but it is like an alarm clock. When it starts to give you a twinge back off. You are probably a weight lifter. You and the cyst can co-exist peacefully as you find out it's limits. I have one too and it hardly ever bothers me now and I have had it for 30 years.
