I had a tiny needle in my finger 5 months ago that has gone deep into not finger now it was too small to ever remove , now it has formed q hard bump and its very painful when i apply pressure.. what can i do to increase healing please ? thank you

It's surgeon time...: Sounds like a doctor needs to examine it to see how to remove the item and the bump. If its depth is unknown, a Hand Surgeon or a Plastic Surgeon likely have the type of experience needed. A general surgeon may suffice, if the other specialties are not available. To start, one's primary care doctor can examine it to get a better idea of what is going on.
