It is an autoimmune type reaction which creates inflamation of the peripheral blood vessels. It is very painful in the tissues in the affected areas. Hopefully that is not what you have and it has went away by now. If not you need to see the type doctors I listed and they would traet you with antiinflamatory meds. Any history of auto immune stuff?
What does vasculitis entail?
Yes that is what it looks like, perfectly round little dots.
It does look like blood under my skin but they are the size of a pin point.
If it looks like blood under the skin and it is all over it could be peripheral vasculitus you would need a vascular d. or a rheumatologist. My mom has that from her knees to her ankle.
