Your description of the sites suggests a trail where the insect(s) has travelled across your upper body after it was picked up, probably at your right hand, following contact with the location where it was at the time. I would be inclined to suggest that a single flea or similar parasitic insect is/was involved. Your description suggests only you are affected, not your daughter. Most bites subside after about 7 days or so and therefore this would have nothing to do with the lice but is more recent. If no new sites come to light then the insect is gone. People's reaction varies in strength and some people scarcely notice any itching but others are driven potty by it and it can last longer than with others. It would be extreme if an insect has laid eggs in your skin, but it can happen, in which case the itch will persist until the larvae exit for their next stage of existence.
