Good day. Spots appeared on my body. I have them. For some reason, I can't add photos. The spots are bright red, I would say scarlet. They look like freckles, slightly raised. They appeared about two years ago, I didn't pay attention. Today I discovered that some of them became larger in size and the number increased. On the internet it is written that there may be problems with organs of the abdominal cavity, but last week I had an ultrasound done by a very good doctor - everything is fine. What could this be?
