"After fingernail injury, what are some treatments to help a fingernail grow back?"
I lost a fingernail after a construction injury a couple weeks ago, and the tissue underneath is horribly sensitive. What treatments are there (if any?) to help the nail grow back as quickly as possible, so I can protect the finger?
An injury to the nail is very painful but encouragingly generally heals well without complications. If you have concerns about the healing process your primary care doctor will be qualified to discuss this issue with you in greater detail. When nails fall off, unless there has been damage to the nail bed, located deep in the fold of the skin below the cuticle) it will generally grow back just fine. Unfortunately, the rate at which the nails grows back is largely determined by the individual person and there is not much that can be done to speed the growth. It is important to keep the exposed skin moisturized and protected from dirt and other potential source of infection. Although it is fine to leave the skin exposed to air, it is often helpful to cover it up with a bandage if you will be working with your hands. It is also important to keep from picking at the healing skin as this can disrupt the process. Occasionally if there is a deep tear under the nail or any imbedded debris this may need to be evaluated by your doctor. As always the diagnosis and the management of your specific concerns will require a physical examination by your personal physician. Setting up an office visit with your primary care doctor might be advised.
