Red bump with red line extending from it. What's this sound like?

Need more info. Where is it? Is it itchy or painful? Is it the only one, or are there more? How long have you had it? This would be a good issue for a virtual consult with an uploaded picture for evaluation. .
Usually. means lymphatic "spread" of an infection..get it checked out with "hands on" examination you may require antibiotics! Hope this helps! Dr Z.
