Skin Problem

[TommyGun]

I have recently developed a skin irritation which started around 2-3 months ago. I don't think it's prinkly heat but if i do anything physical, i come out in small red blemeshes down my arms and especially on my back. They're quite itchy on my back for a few moments mand they almost look like faint beauty spots and spaced in a similar way.

I also have granuloma annulare which i havent suffered from while being in Thailand. I'm sure the condition described above is not the same. Doesn't look the same anyway.

Can anyone recommend a place, and what is the cost roughly for an allergy test. I'm in Silon Area.

Thanks
