@tony Yup it can Hurt.
I got stung in the hairline just as you said and my eye swelled up as well!!
It seems to depend where you get stung. On my fingers- a little swelling on my hand Loads of swelling on my scalp no swelling. Lose and soft skin seems to swell more tough skin and next to bone less.
In the beginning I used to swell up and itch for a good week 10 days - now I hardly notice it after a day or couple of hours… GP told me to take Piriton http://www.boots.com/en/Piriton-Allergy-Tablets-30-Tablets_11235/ for a week after the sting and I did that for about 2 months - now I don’t need it the reaction is almost nothing?
Anaphylaxis and Bee Sting Allergies hope this helps
