Hi all just a quick question really over last 3/4 days we seem to be getting these spots both me and ds had them first but dh has them now too they come up singularly and very itchy after which they scab and dry of. they arent in any clusters or anything obvious otherwise fine and well just wondering if we getting bitten by something. all bedding gone in wash sofas been vaccumed and cleaned. no pets in the house. just not sure what they are? TIA
