I am sick of them! I have scars from insect bites on my legs going back months!! I got bitten on the weekend on two different parts of my leg, so there's two awful marks on each section (fangs I guess...), they're bumpy, red, itchy, of course I've scratched them and now look awful!!! I'm going on holiday in 4 weeks time and now I have unsightly bites which I know will last forever. What can I use on them to help the healing process and how can I prevent insects from biting me in the first place??
