Weird spots

I’m just posting on this in the hope that someone can help me. My partner pointed out some itchy spots on his back, unsure on what they are but keeping an eye on them and possibly a trip to the doctors tomorrow, but I’m just looking for some advice, do they look like chicken pox? He has already had chicken pox as a child, although I know you can get them again! The picture of most of them are in a line, so made me think about shingles?

Thank you in advance 😀
