A doctor will examine the lump carefully, because any swelling on the neck should be checked by a professional to be sure what it is.
If it is a cyst, it is numbed, opened with a small cut and drained, and the sac is removed so the cyst is less likely to come back.
The area is then covered with gauze, kept clean and watched for redness or warmth while the skin heals.
Shaving with a clean, sharp razor, washing the neck after sweating and not squeezing bumps all help prevent new cysts.
Keep the faith and take care of it early. The videos below show cysts on the neck being treated by professionals.
