I was at the beach about a week ago and just got back. In the last couple days there while we were in the water my brother, dad, and I started feeling these stings like little bites. We finlay figured out that there were small jelly fish in the water. When we left there were little red bumps on out skin, they didn t hurt or anything and went away after an hour or so. Im back home now and it s been about three days and two days ago I started getting these little red bumps again. They are in different locations, mainly on my legs and a couple in my arms. There are single bites and there are bites in groups of three or four. These ones itch. The itch is gone during the day and comes back at night for some reason. I went to the doctors yesterday and age said it was probably sand flea bites. But I didn t think that made sense since is broken out in them after coming home from the beach. Oh and my brother and father got then too at the same time.
