I have been feeling strange sensations on my back for the past few days and I can't seem to figure out what it is.
I've been feeling strange, prickly feelings all over my upper and lower back, my waist, and sometimes my neck and the lower part of the back of my head. It starts off as a prickly, sometimes stinging feeling. Then it gets really itchy, and if I don't scratch it, it doesn't seem to go away. But if I do scratch it, it leaves for about a half an hour then it comes back. I'm starting to see a slight rash on my lower back and parts of my waist. It occurs both when I'm sitting down or standing up. So far it hasn't happened while I was lying down. I think it might be scabies, though I'm not sure and I can't seem to find any diagnosis that contains all of my symptoms.
I'm a male of 15 years old, I go to a public high school where there is constant skin-to-skin contact. I wash daily so I don't know what could be causing this. Any help?
