I don’t know if this falls under the category of “soliciting medical advice;” it’s not something that most people would see a doctor about.
My partner returned from a business trip to Milan, with what look like large mosquito bites around his waist. He’s been back about a week now, and they haven’t gone away; nor are there any new ones. They are only around his waist, and he says they itch, but not as bad as mosquito bites.
I’ve never heard of an insect bite that would be unchanged after a week. What could they be, and will they go away by themselves?
