Woke up Saturday morning after spending Friday evening outside at a BBQ with about 3 little spots on my neck, thought originally bites. Gradually throughout Saturday and yesterday I developed more, mainly in pairs, on my neck, arm, back, and tops of my thighs. I now have about 15-20 in total. Yesterday I began to feel unwell with a very sore throat, headache and shivery. A couple of the spots have blistered (pictures attached).. been trying my GP surgery all morning, lines engaged. Worried it's infectious as DSis is currently pregnant. Any thoughts / suggestions? (I will obviously speak to my own doctor but just looking for advice)
