Hi Dunny, i hope thats how you spell it
I sometimes would get these and still do, and I find its from wearing mascara and eyeliner, the only time it is painful, is when they break, and it kind of stings, but it is also uncomfortable when closing the eye, but doesnt hurt, thats how I know if i have one. My mom told me that it could be from the makeup, so i stopped wearing it for a while, and sure enough, they stopped coming. Im not sure if this is what your experiencing, but it may be worth the thought.
Hope this helps atleast a little bit
