I'm prone to boils and they used to come and go. they're back but they stayed for 3 months now. i don't know if i should go to a doctor so i asked this website?

You are likely a carrier of invasive staph germs. They often reside quietly on your nasal membranes. Adults randomly touch their face/nose hourly. Random touching eventually spreads them to places you touch/scratch. A doc can put you on oral meds and a protocol to end your carrier state.

Yes, definitely a good idea to see your doc in order to get a diagnosis and proper treatment. Such conditions may become refractory and initiating proper treatment may help. Your condition is suggestive of hidradenitis suppurativa among others.
