I have a very swollen foot where something has bitten me. It started at the weekend when I noticed a small black beetle type creature on my ankle. At the time, I just brushed it off and thought little more of it. Now, however my whole foot is swollen and is covered by a very itchy and painful rash which surrounds a single puncture wound on my ankle. I'm not entirely sure what the creature was that bit me, but this is a different type of insect to the normal ones I have. It seems to be more painful and it is taking longer for the swelling to go down. Do you think you know what it was that bit me, if so let me know here?
