Posted on Fri, 19 Dec 2014
Question: I injured my middle finger back in July and needed stitches. It seemed to heal up fine after a few weeks and all was okay. However this morning I noticed that my finger in the same area where the injury occurred has turned black and blue and is feeling numb

Brief Answer:
An injury is likely.

Detailed Answer:
Hello,
Thanks for posting your query.
The black and blue finger can be due to a repeat injury in the same area. The finger stitched up in July must have healed well by now.
The black and blue coloration indicates a hematoma formation in the area. It can cause a local nerve compression causing the numbness.
If there is no acute pain on bending or the swelling is not actively increasing then any bone injury is not likely. You can strap the finger with the next finger and let it heal on its own. In case it is painful and tender then an infection needs to be ruled out after a direct examination.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Wishing you good health.
Regards.
Dr. Praveen Tayal.
