Something came on my cheek,when I tried to squeeze this thing, only water or oil came out,I have been doing hot compress on it, now the place has healed over,but when I turn my head ,I can see a round puffy something about the size of a quarter,it isn't hard,doesn't hurt, last week another one came on my forehead, never squeezed the last one,just a small pimple,but same as first one,you can see a place that's about the size of a dime, perfect circle under the skin,not red,not tender, first one has been on my face for about 3weeks the 2nd one for 4days, what is this
