While nowhere near your territory, I've come to keep my antihistamine tablets on hand all year round as somewhere between the 'my skin being quite sensitive' and the 'aspie touch hypersensitivity', I'll occasionally spontaneously get intense itching all over my skin. And this is all year round, not just in my normally hayfever season.

VERY VERY appreciated when needed.

...but then I now have a long stick of those small screw together travel pots which acts as a micro-pharmacy for all ills in my handbag...
