I have bites on my face legs arms and back. They don't know for sure what type of bites they could be. Bed Bugs or Sand Fleas. I went to Myrtle Beach and stayed at the Sea Watch resort. The first day I had one bump on my breast and t hen 2 days later I had so many bumps popping all over me. They itch really bad and the bites are swelling. The doctor told me to use benadryl and cortisone cream. Now they are extremely large and red. Some of the bites are in a line, some are sparatic all over my back.
