I went to a restaurant yesterday (all you can eat, world wide food type establishments). Whilst coming to the end of my chinese platter (noodles, chicken piece in black bean sauce, sweet and sour chicken, stir fried mushrooms, satay sauce and a pork rib) I got an itchy arm. I had three 'bite-like' eruptions on my right arm. I went to get a pizza slice and by the time I came back, I noticed my left arm had erupted on the forefront arm and back. On leaving we told a member of staff as we thought it was there cleaning fluid but 15 minutes later whilst in a lift in a shop, I noticed in the mirror that I had erupted on my chest. Within the hour I had small bite-like eruptions in various places but quite far apart but my joints were somewhat stiff.
Anyways, I arrived home to find that my left hand was swollen, the bite size eruptions had spread into huge red welts, I was itchy in places that didn't have the rash but my joints - hands, wrists, elbows, shoulders, hips and knees were stiff and painful. Buy this time huge red welts were appearing in other places.
A restless night and the rash has spread all over my chest, back, legs, scalp and even my bum!! It's starting to creep up my face.
I have taken antihistamines as I am on them for chronic rhinosinusitis but it seems to have had no effect.
I thought 20 hours after they first appeared they would have gone, especially if food related, but it is worsening and has spread. Apart from tiredness, i have no other symptoms - no breathing difficulties etc.
Does it sound like a food related problem or possibly viral? I am at a loss. Never ever had any issues like this before.
