I have a similar sist. All of a sudden one morning, I woke up and it was very sore and swollen. It is hard and also a little smaller than a marble. I was not on any cycle at the time and had not been for 4 months and that cycle was just winny and tren. What causes this? Is it gyno? The swelling has gone down some, but it is still very sore. Thanks for the help.
