Do These Look Like Bite Marks?

[Coco&Luna]

For about 6 months i've been getting spots on my arms legs and stomach. They're like red heat spots and are REALLY itchy. The itch gets so much worse when i scratch them. I'm not covered in them but i have about 10 spots just now and they're mega itchy. I feel too daft to go to the doctors about it because it's only a couple of spots at a time.
Luna has been treated with xeno because i thought it might be something she had & i know it's not stanley because it's been going on long before i got him.
I don't know if it is just heat spots that I'm making worse by scratching because i dont know what else could be causing it.
My OH's dog and cat are all flead and wormed, so i dont think it's them.

Sorry in advance for the crap pictures, hairy legs & harry potter socks. LOL

My mum had those sort for about a week then it went. It could be something picked up from outside.

I thought that too, but because i've been getting them for like 6 months I'm starting to worry it's something in the house. I actually thought I had bed bugs and started searching my matress with a magnifying glass like inspector morse. haha

I'd go to your doctor because 6 months is a long time
