I Have An Unusual Problem, Where An Artificial Substance Is

I have an unusual problem, Where an artificial substance is developed underneath the skin and it was sticky to the skin from inside where it is created. It was like "bean"; shape of ball with ( hard crystal solid ) with no pain and no sign itching and tenderness. I am absolutely normal with daily routine before and after it got developed nearly 6-8 months.The sad part is it was developed near Cronin area where scrotum skin starts under lower abdomen. on research i came to know that it is "sebaceous cyst" on scrotum skin. It was nothing to do with my testis,my reproductive is entirely normal and fine and absolutely routine it was just beneath of skin.I am happy to hear any suggestions where do i need to undertake any surgery to remove it or it can be cured with medication.
