Every time I get an insect bite the area around it goes through a complete over reaction. The bite will swell massively as will generally at least a 5 cm circle around the bite. It will also be unbearably itchy and sore. Anyone else experience this and found anything that works? I am already on antihistamines for hayfever and have taken piriton. I've tried aloe vera, hydrocortisone, anthisan and after bite (plus more probably). Been bitten on my hand yesterday and struggling to move all fingers now as swelling is so bad
