Sebaceous cysts are often the result of swollen hair follicles, or skin trauma. Treatment of sebaceous cyst (or epidermal inclusion cysts) will largely depend upon whether they’re inflamed or infected. The cyst will not go away on its own , and would occasionally flare up thus causing pains and discomfort. Inflammation occurs when the cyst ruptures into the tissue, and only the cyst cavity is usually red. To control the infection of sebaceous cyst, antibiotics will be required, in most, to cool off the pain & discomfort. Infected cysts should be very conservatively lanced and drained, and allowed to heal, but coverage with an antistaphylococcal oral antibiotic is helpful in most situations. However, before taking any action I recommend seeing a medical professional to know exactly what is the cause of your issue.
