About 6 weeks ago, I felt a small round bump on by back. I asked my husband to see if it was a pimple and if so, could he pop it for me. He looked at it, told me that it was a small raise red dot and he didn't think it was a pimple but did squeeze it a few times to see if anything came out. Nothing. A week later, I noticed that it had gotten larger (again, not really being able to see it), my husband said that maybe it was a pimple after all because it looked like one but didn't have a visible head. He squeezed it a few more times and then pricked it with a sterile needle. blood came oozing out but no puss. he didn't squeeze it again, but had to put pressure on it for at least 20 min and even then, I had to put a bandaid on it because it was still bleeding. Over the next few days, it got larger and larger. What my husband said was once a small red dot the size of pea maybe, and raised above the service, was now at least 1/8 inch high and about the size of a penny. It started to scab over, so I left it alone. Until one day, I was laying on our leather couches, and my skin was stuck to it and when I went to get up, I immediately felt dripping down my back. It took almost 1/2 hour to stop the bleeding that time. When I went to the couch,(sorry for the grossness), stuck to the couch was a big ole' scab. Crusty with edges especially dry. This happened one other time, when I forgot, and scratched by back really hard. I know have what looks like a blood blister, but it starting to get crusty, especially the edges, which are pulling away from my skin and are completely hardened. Where the very center feels kind of mushy, putty like. It feels like If I gently worked on the edges that were already releasing, the rest might release as well. Just don't want to make it worse than I have.
