Is it normal you mistake an insect(parasite) clinging to your back as a scab?
I sometimes get acne on my back which is really annoying. However one of them was really big and on the back of my neck. It was the size of dime. I figured it was just more acne but it was hurting for awhile and very irritating. I finally managed to pull off the end of it. Which I figured was the tip of the zit. However when I pulled it off it felt like I pulled something bigger and I felt blood running down my neck. Is it possible I had a tick of something on me without realizing it and just yanked it off? Since that point the lump has become smaller and finally went away.
