Should you be worried if you had a small bump on your belly and scratched it and now almost 3 weeks later it's black about the size of your pinky finger and has a lump underneath?

It’s important to have any unusual skin changes evaluated by a healthcare professional, especially if a bump has changed color, increased in size, or has a lump underneath. While it may not be serious, these symptoms could indicate an infection, a cyst, or other skin conditions that require attention. It's best to seek medical advice to ensure proper diagnosis and treatment.
