I've developed raynaud's. Also have livedo reticularis all over my body which seems to be getting worse. I know these can both be primary conditions, but should I be worried about an underlying issue?
Systemic disease. Yes, see a rheumatologist for a complete workup.
See a Rheumatologist. This is a uncommon condition which should be handled by a specialist who deals with collagen-vascular conditions . There can be an underlying cause which requires detailed investigations to rule it out. That is where your rheumatologist/consultant can make an important contribution to your welfare.
