I just spent a week in Florida working and after being out one evening I ended up with these large red welts on my feet that itch horribly. I was staying in a hotel, so I thought bed bugs, but I didn't end up with anymore the rest of the week. Also, after my first night home I woke up with two of the same welts on the inside of my right thigh, so that sort of threw my bed bug or mosquito theory out the window. As of today which is 4 days since the first welts appeared they are still present and have not gonedown. Please help and yes this has happened before but not to this extent.
