I have had a very small under the skin area between my eyes more to the left at the beginning of my left eyebrow. For over a year, it was almost unnoticeable. Now, over the past 3 days it has become red, swollen, sore and so very painful. There is no head on it, just hard and sore. I have been leaving it alone. Don't want to infect it. I have applied a hot compress a few times and that helps a bit, with the pressure and pain. What is this? My research has led me to a facial cyst. I just don't think that's what it is. But it's making my left eye swell up too. Going to Dr today.
