A doctor will look at the swelling, feel its edges and ask how long it has been there. A large, tender lump on the back should always be checked before anything is done to it.
Treatment usually means numbing the skin, making a small opening and draining the contents. The cyst sac is then removed so the lump does not simply fill up again.
Afterwards the area is cleaned, covered with gauze and checked again in a few days. Keeping the dressing dry and clean helps the skin heal without problems.
Washing the back well after sweating, choosing breathable clothing and not squeezing bumps all lower the chance of a new blockage forming in the same place.
