On Friday, November 21, 2013, i received a "bite" on my neck. It began itching immediately and i showed my husband and we both thought it very odd on a cold, rainy night....our adult son, his wife & infant all with us and no one else received a bite. my concern is this: have taken one antibiotic, used antifiotic cream and now a predisone cream and the bite still looks like I just got it. the shape is almost triangular.
