How long does it take for a polinidal cyst to come back after being popped and negative cultures. with antibiotic treatment.?

Recur: Pilondial cysts have a tendency to recur, unfortunately. The cyst wall stays behind, even with rupture and antibiotic treatment, and the cyst can reaccumulate. In order to properly treat a pilonidal cyst, the cyst wall needs to be completely removed. Either your primary care physician or a surgeon can perform this procedure.

Sometimes, never.: Pilonidal cysts are areas of chronic inflammation overlying the tailbone that arise due to ingrown hairs under the skin. These are prone to infections that form abscesses, requiring incision and drainage ("lancing"). Surgical excision is reserved for those that require repeated lancing, since these may recur as often as 25% of the time even after surgery. Fortunately, these are rare after age 30.
