The doctors informed me that I am a
MRSA carrier and I have to take antibiotics a week before and after any surgery. As
for why the cysts always get infected, typically when the cyst is located at a high friction area like your groin or hips, it inflames the gland.
Hope this helps. As far as preventing them, I haven't found anything that works. The doctor said I'm prone to them and will continue getting them for the rest of my life. It *****, but at least they're not cancerous.
