Ta @Caesardust and @Petal40. I just tried some burns cream (burnaid) on it hoping there might be some anaesthetic in it for relief but nope still on fire. I almost feel like my body is screaming at me to stop putting cr~p in it. It's had enough. Antihistamine delivered to my door right now would be a god send!!
(apologies for the whinge @Precious40 when you're having such a hard night).
