The kindest help at home is gentle: cleaning the area, using a warm compress and covering it with a fresh pad instead of squeezing.
Pressing hard on a cyst can push the contents deeper and spread infection, which usually makes the swelling bigger and more painful.
A doctor can numb the area, open the cyst safely and remove the sac, so it does not keep coming back in the same place.
Afterwards, a little care each day, such as changing the dressing and keeping the skin clean, helps it heal quickly.
Little things really do count. The videos below show back cysts like this one being treated by professionals.
