I have a bump in the middle of my foot and it is hard now there is a red line what does this mean?

Could be a varuca faruca however you spell it. anyway its not that bad had it before you could get several more as it is highly infectus. go to a doctor and make sure it is removed properly a knife is what was used with me and it wasnt kept clean by the doctor when he was doing it i woke up the next morning with 9. get it done right if that's what it is
