woke up with a small bruise under my eye for no apparent reason... but I also ( for months now) feel like I have pressure behind that same eye. Sometimes it wakes me up at night, especially if I lay on my left side. And I haven't been able to wear my contacts for more months - I go months without wearing them, then, when I do try to wear a new pair, I can only wear them for a couple of hours. I do have allergies, and occasionally get excema on my eyelid. 48 year old female in good health
