I have a sore white bump under my skin on my finger tip and there's redness around it. it is painful to touch?

WHAT'S YOUR QUESTION: MY QUESTIONS ARE: HOW OLD ARE YOU? HOW LONG HAS IT BEEN THERE? WHICH FINGERTIP? WHAT DO YOU DO FOR A LIVING? HOBBIES? SINCE I CANNOT SEE YOUR PROBLEM, DO SEE A DERMATOLOGIST SOON. BEST LUCK.

Diagnosis: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
