Does anyone know what this can be ?

It’s been going on for about 2 weeks now. It feels like a mosquito bite but it’s everywhere and only itches a little. The first time I got it it happened by my waist line and I thought it was my biker shorts because maybe they were a little too tight? Then the next day it was by my elbow area and today it happened here on my shoulder. Whenever I get it it only lasts about 30 minutes and it goes away like nothing ever happened. It’s always me, my partner and our son together in our room and it only happens to me. Should I see a doctor?
