I have what looks like a rash but up close looks like little red vains all over my chest (above my breast, below my neck) what could it be?

Hard to tell. Diagnosing skin conditions is best done be looking at the lesions.
Lacey rash. A lacey rash on an adult could be a parvovirus infection. If you have liver problems, it could be spider veins (telangiectasis). It could be just age-related. Definitely worth seeing a doc for this.
