What can cause red/dark red vascular painless lesions on one toe? ive had a few for a year and then another one appeared so its progressing. its not raynauds. i was told only that its vascular/blood flow. appreciate any thoughts?

Painless lesions which have increased in size(plus additional new ones showing up) would be concerning to me. So you should show it to your doctor or go to see a podiatrist. He may recommend a biopsy or take a photograph for future comparison for further growth. Vascular lesions can be a benign Hemangioma or on rare occasions an Angiosarcoma. So I would not delay the necessary check up.
