I have a few red/blood looking spots on the roof of my mouth, is this something I should worry about?

Hi,
The roof of my mouth slightly near the middle I have a few red/blood looking spots. I’ve only just noticed them today. The roof of my mouth has been itchy all day and only seems to of just occurred. One of the veins at the back of my throat is also looking really dark purple.
