Scratches appearing on my arms without scratching myself

Scratches appearing without scratching myself first one looked like a welt inner lower arm but underneath was small scratches  went away after a few days   got another one 4 days later.  there was a red dot of blood that came to the surface  I have a few  of these red dots on my calves and one on my arm. New scratch now is right over that red blood dot no bleeding. No itching.  My doctor thinks it’s nothing that I am being anxious over a scratch I probably scratched myself now I have another little one on my other wrist just looks like a small scratch.  Gets very red and then goes away after a few days. This is freaking me out I have an appointment with a dermatologist but not until August 14

I'm glad you have an appt with a derm.

There are a few conditions that can cause things like this - https://www.healthline.com/health/waking-up-with-scratches#scratches-from-a-pet-or-another-person (They include a section on the paranormal, and I don't know why - you can ignore that part.)

One of the conditions listed in the first article is dermatographia - https://www.mayoclinic.org/diseases-conditions/dermatographia/symptoms-causes/syc-20371411 They include a photo, which has scratches ALL OVER. I am not familiar with it enough to know if it can only cause a few scratches, or it needs to be all over the body like that.

In any case, none of them sound serious, which is the good news. :)
