If it is a cyst, the patient lies back comfortably while the doctor cleans the skin and numbs the area with a local anaesthetic.
Using fine instruments, the doctor opens the cyst, gently releases the contents and removes the sac so it does not grow back.
The neck usually heals well, and a small dressing is often all that is needed for the first few days.
Keeping the area clean and avoiding tight collars or rubbing helps the skin recover quickly.
Keep calm and carry on, because most problems have a simple solution. The videos below show neck cysts being treated by professionals.
