However about a year ago, whilst visiting a friend, I woke to an itchy
eyelid, not much , just a little
red patch and itchy. I thought I had been bitten in the night, it didn't amount to anything and cleared up. Several months later, it happened again - I woke to find a slight red patch on my eyelid which on standing up, literally filled up with fluid as I watched and just got bigger for a number of hours! Usually lasts all day and has almost gone down on day 2.
