For the last 6-7 months I've had these red/purple marks around my lower stomache and groin area. There are smaller, thinner line like marks near my collar bone/shoulder area. These marks indent like a grove and are slightly sensitive. They do not itch or hurt.
I sit down for most of the day so at first I thought that they were result of that. They haven't gone away but some on my legs are returning back to normal.
Any ideas on what this is or how to treat it?
