Well, the area around my right eye is now so swollen I can’t open my eye, which makes putting the drops in a trifle difficult. I can’t even force it open with my fingers.

Have you previously had a reaction to a beesting? (I read back to when I left for archery). This sounds like quite a severe reaction. Mr buffy thinks it might be wise for you to go to accident and emergency and get it looked at. If you were going to have breathing difficulties (anaphylaxis), it probably would have happened earlier than this. And you probably need to talk to a doctor about maybe having prophylactic medication on hand for your next beesting, as it seems your system is primed to react and may well be worse if you get stung again.
