What should i do if my pilonidal cyst popped itself?

Pilonidal cyst: I would still have it checked as pilonidal cysts often recur. Surgical intervention may be warranted.

Temporary relief : If it pops and drains you may feel better within a few days. This takes the pressure of and may help the Acute infection. If you're lucky it won't flare up again for a few years. However, if you don't have the cyst excised it can recur over and over again.
