Around a week before one small pimple like structure i have seen on my stomach. Within next 2/3 days it became a big boil. And then it started replicatinga nd now they are 3 below breast. 2 on the upper back and 2 at lower back. Addition to this I started going fo swimming at the same time. seocnd point i ahve heat problm in summer as very often i see it around my lips. I am not sure if its because of too much heat as due to hectic schedule i only sleep for 5 hrs. mostly. Those boils are paining
