What is this circular bump on my finger
Help what is this 🤮This just appeared on my finger over the last week, it’s not sore but kind of stings when I press down on it. Also seems to be getting bigger. Could hit be contagious? I really don’t think it’s a wart. I thought at the start it could be a burn from oil spitting at me when cooking the dinner. Only any other burn I’ve had Dosnt have a red dot in the middle….
