As in typical BEB fashion, I just composed this wonderful post to you and then at the blink of a unrestrained finger, I clicked something(who knows what) and it was gone in a flash. Never to be retrieved or relocated-just pure and simply GONE.
So here goes again.
My first thought is that you might be developing a stye but they tend to be tender and painful. I'll go with that first, anyway since you mentioned some swelling. Many people get them and they are merely an infection that occurs either on the outside of the eye or sometimes the inner lids. Redness, swelling, tenderness and pain go along with them. They can last for varying lengths of times, usually days. It is more of a localized infection and treatment usually consists (like June was saying) of warm moist washcloths to the affected eye several times a day. This is just a means of getting the stye to come to a head quicker and drain in which case it will then just go away. Antibiotics are generally not very helpful with styes.
It also could just be a localized reaction to any number of things. For those of us with BEB, I know that my hands and fingers come in contact with my eyes much more than they used to. With hands and fingers come bacteria and allergens and all kinds of things that don't usually get in our eyes or at least not as often. And like you said, Joanne, botox loosens the lids and we don't blink as well as we should, thus allowing other irritations to develop. In this case, you might want to just use more preservative free eye drops to keep things clean and washed out as much as possible and try to keep fingers away and keep your hands washed more often.
I would call your PCP about it and see what they have to say. They might recommend a different drop, maybe an anti-inflammatory drop or antibiotic drop.
Hope this helps some. No charge for an email call. :-) Possibly a visor. :-)
