Can I ask what your symptoms were before it turned into an anaphylactic reaction?
My drs are a bit shit and dismissed me last year saying it's just what happens with a wasp sting but this is what happened..;
I got stung on leg by a wasp in November in the morning. It hurt a lot. No biggie.
All day I had electric like shocks from the sting up my leg, up my back into my neck, I'd say it happened once every 5 minutes with goosebumps every time.
Later that night I took my trousers off and the sting was a red area 8 inches wide and the same long. It was raised and sore for days. Antihistamines helped a bit by the shooting pains terrified me.
Do I need to go back to the drs and ask them for an epi pen? I know wasps are fairly rare but it was such a scary experience- not the big welts or the initial pain but the shooting pains and goosebumps every time it shot up to my neck. Or was it just a fluke that hit a nerve?
