OOO i have the exact same thing i'm not even kidding i have something that looks as though it is an insect bite on the back of my left hand its slightly raised and yesterday when i noticed it it was really red and looked horribley raw, but today it has just became a lump and a bruise. but there is another mark below it too but with no puncture mark,
where as on the lump there is too. i panicked and thought it was something serious and i still cant find any info on marks like these, the puncture wound is dark too. i think it must be some kind on gnat, or mosquito. only something small could make that smaller mark,
i've had mine fore two days now and its beginning to swell a bit bigger each day erm do you think i should see someone. i used a healing cream for skin complaints on it but that really didnt have any effect to be honest. i'll try looking through some more sites and if i find anything i'll leave another comement.
