a visit with a primary care dr isn't really all that expensive, and most are willing to work with you as a cash patient... i know my parents' family dr sees them for like $50, now that's the visit itself, NOT any labs/testing. call your dr and explain the situation. btw, MANY ppl have visible veins and you're saying it's visible NOW, who's to say it was even visible then? DRs don't examine every little thing. it sounds like you are probably heavy and need to eat healthy and exercise a little. i'd drop the gym membership and use that money for a DR visit personally, walk around the neighborhood everyday for exercise. the veins are likely "nothing", but get it checked if you're that worried - the peace of mind will do you good, you're gonna work yourself up and cause some other health issues. take care of yourself and get to the DR.
EDITED TO ADD: hmm... just to "get to know you" a little better, i looked at your past postings... a week ago you talk about airline tickets and $700 in cash for as surprise, yet you "obviously" can't go to the DR? sounds like a priority check is in line...
