For the past few days (5 days) I have this redness on the outer part of my left eye with sort of a pimple/cyst looking bubble in the centre of the redness. It has reoccurred a couple of times but, this time it hurts slightly and has remained/stayed longer than usual. Please advise, I did see my GP the last time it came & was advised it will go away, & it did, now it's back again. I wear spectacles for reading & distance. Gazza.
