Bacterial infection
Hello Doctor: My big toe became red and swollen after I cut my nails too short, and it started to hurt a lot.
I also developed a pus-filled bump.
I went to see a doctor, who diagnosed it as a bacterial infection and prescribed oral medication.
Now that I've been taking the medication, the swelling has decreased and the pain has lessened, but the area where the pus was and part of the nail have turned black.
In addition to the discoloration, there is a hard lump in the area of the pus, and there are cracks in the nail.
Is this a normal phenomenon? Do I need to return for a follow-up appointment? Thank you!

The dark coloration is most likely due to a scab or dried blood clot; if there is no pain, it is not a cause for concern.

Dear Reader,
Thank you for your inquiry regarding your recent experience with a bacterial infection in your toenail. It sounds like you have been through quite a challenging situation, and I appreciate your detailed description of your symptoms and treatment.
From what you have described, it appears that you initially developed a bacterial infection due to cutting your toenail too short, which led to redness, swelling, pain, and the formation of a pus-filled blister. This is a common scenario, as trauma to the nail or surrounding skin can create an entry point for bacteria, leading to an infection known as paronychia. The fact that you have been prescribed oral antibiotics and are experiencing a reduction in swelling and pain is a positive sign that the treatment is effective.
However, the presence of blackened areas around the pus-filled blister and the nail, along with the hardness you mentioned, raises some concerns. The discoloration could be due to several factors:
1. Necrosis: The black color may indicate tissue death (necrosis) in the area affected by the infection. This can occur if the infection was severe or if there was significant trauma to the nail bed.
2. Subungual Hematoma: If there was bleeding under the nail (subungual hematoma), it can also cause a black appearance. This is often accompanied by pain and pressure under the nail.
3. Nail Changes: The cracks in the nail and the hard area you feel could be due to the infection affecting the nail matrix, which is responsible for nail growth. If the matrix is damaged, it can lead to permanent changes in the nail's appearance.
Given these observations, it is crucial to follow up with your healthcare provider. While the reduction in swelling and pain is a good sign, the changes in color and texture of the nail and surrounding skin warrant further evaluation. Your doctor may want to assess whether there is any ongoing infection, necrotic tissue that needs to be removed, or if there are any other underlying issues that need to be addressed.
In the meantime, here are some general recommendations for caring for your infected toenail:
- Keep the Area Clean: Gently wash the area with soap and water, and keep it dry. Avoid soaking your foot in water, as this can exacerbate the infection.
- Avoid Tight Footwear: Wear loose-fitting shoes to prevent additional pressure on the affected toe.
- Monitor Symptoms: Keep an eye on any changes in symptoms. If you notice increased redness, swelling, or pain, or if you develop a fever, seek medical attention promptly.
- Follow Medication Instructions: Continue taking the prescribed antibiotics as directed, and do not stop the medication prematurely, even if symptoms improve.
- Avoid Self-Treatment: Do not attempt to drain the blister or remove any tissue on your own, as this can lead to further complications.
In conclusion, while it is encouraging that your symptoms are improving, the changes in color and texture of your nail and surrounding tissue are concerning and should be evaluated by a healthcare professional. Regular follow-up is essential to ensure proper healing and to prevent any potential complications. Please do not hesitate to reach out to your doctor for further guidance and to schedule a follow-up appointment.
Best wishes for your recovery!
