Question: blood dots

I was sort of unsure about where to post this question. Anyway, on my upper arms, there are many tiny red dots. It's looks as though blood has leaked through the skin. Most of them are tiny dots, but there are a few that are a few millimeters thick. If I poke them, they pull back into the skin, then come back out in a few seconds. They are not raised. I'm just wondering what these things are. They have been there for a while now. I do have high blood pressure. The only place I've seen them is on my upper arms. Thank you!

User avatar Hi Stjimmy,

If I am understanding you correctly, when you press on these dots they loose their red color then subsequently regain the redness. This is called blanching.

If the spots blanch they are likely to be either a rash or possibly some capillary beds that are near the skin. Given that you say they have been present for a while I suspect that these may be small capillary beds near the skin (known as capillary hemangiomas). These are harmless.

I would recommend you have your doctor take a look at this when you're in the office next time.

Best wishes.
