Went Rugby training last night, got eaten alive! What do the little bu66ers leave behind that makes you itch so much? Some sort of minor infection presumably but what makes it itch??
Try using antihistamines they work with mosquito bites but you have to take them before you're bitten. See the pharmacist for some cream to put on the bites, hope this helps.
As a matter of interest, exactly where is your club. I have found that gnats vary according to locations and would like to pin-point places most vulnerable.
