No not everyone have drains as it depends on each surgeon and what they prefer to use some like to use strappings some like to use drains some like to use no drains or no strapping…
The purpose of a drain is to get rid of any build up of unwanted fluid post surgery a tiny incision on both sides r made and are gently removed by a nurse afterwards…
Drains are just a pain when you need the loo! Just a weird feeling coming out. It’s peeling the strapping off to get to the drain that hurts as it’s really sticky then.
