Re: Bad reaction to sting?
That the old sting site on your temple reacted after the latest sting could indicate your body is building a "memory", or in better language, an immune response that could lead to anaphylaxis.
Would definately consult a Dr, not a general practitioner who will doubtless just recommend you carry an epipen, but if you can go to a proper immunologist who can run tests and find out exactly what is going on, and wether this is something you will overcome naturally, or wether it will worsen every time.
Some words of comfort, i am a retired commercial beekeeper and have had thousands of stings and no longer react at all. But when I first started i got major swelling just from one sting, and have also had experiences like yours where a different sting site would react after a sting in another place. However luckily for me, my body reacted right and symptoms gradually got less with more stings. So you may get over it naturally, but in my view, would pay to have some professional advise.
