To confirm the fungus you can do fungal lab testing and will be treated by either tincture such as Penlac
1) That after removal of the nail there was some damage to the nail matrix (the "root" of the nail). The matrix cells are now arranged such that they will continually grow put abnormal appearing nail due to previous damage.
The solution to this problem would be removing this portion of nail again and applying a chemical to prevent this portion of the nail from ever growing back (a matrixectomy). This is done in office and is almost exactly like the procedure you had done previously.
2)This could be a bacterial or fungal nail infection. If this is the case you would have a nail sample tested to see which organisms are causing the infection and treat with an appropriate topical and/or oral medication.
I hope this answer was helpful,
It is a frustrating disorder and unfortunately no definitive treatment to guarantee return of your normal nail appearance.
The other option, while being more radical, is to completely remove the nail, kill the root, and once it is healed, you can apply a false nail or a nail polish with nail bed adherent.
If you choose that option, there will be no functional deficit as other then cosmetics, the nails in humans serve no functional purpose.
Hope this helps.
The only way to truly know if your nails have fungus is to go to your podiatrist, have a nail sample taken and submitted to a lab for identification. The lab will be able to differentiate whether there is fungus present in the nail or not. If there is no fungus, your nail bed was damaged by the nail procedure and may take time to improve, or may never improve. If there is fungus present, it is harmless (an estimated 38 million Americans have nail fungus), but can be treated with either topical antifungal medication or oral antifungal medication.
There are usually 3 reasons why you could have developed this problem:
1. If the nail bed had been damaged during the procedure.
2. If you had suffered any injury to the nail bed during the healing, until the new nail grows back fully.
3. If you had developed nail fungus infection to the nail bed during the time of healing.
There are multiple things you could try to improve the appearance of the nails, but first you need to have nail biopsy performed to determine if there is actual fungal infection. Nail bed reconstruction could be performed if there is no toe nail infection. If there is fungal infection, then you have options of topical antifungal meds, oral meds, laser treatment, total nail removal with nail bed reconstruction.
I hope this was helpful. Let me know if you have anymore questions.
