Can nail melanoma cause grayish-blue discoloration of toenails?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I have four-month-old twin girl babies. After delivery, I got a blood clot under the left toenail. Another toenail shows a light shade of grey color. I do not have pain. But sometimes, I am not able to walk. I am afraid of this issue. All corners of my fingernails have become blue after taking Onabet lotion. But there is no cure.

Now, I have been taking Zincovit syrup and Triboost tablets for the past two months. I am using Sertaconazole nitrate lotion on all my fingernails. I have a height of four feet eight inches and a weight of 126 pounds.

Please suggest.

Thank you.

Hi,

Welcome to icliniq.com.

Based on your description, it sounds like you have onychomycosis, a common fungal nail infection. You are already using the right medication, which is a great step toward recovery. However, it is important to remember that nail fungus takes time to heal. Toenails grow much more slowly than fingernails, so full recovery can take around seven to eight months. If you are taking antifungal tablets along with topical treatments, the infection may clear up faster.

In the meantime, be patient and consistent with your treatment.

To improve your chances of a quicker recovery, try to keep your nails dry as much as possible, as fungus thrives in moist environments. Reducing water immersion, such as prolonged soaking or excessive washing, can help prevent the infection from worsening. Also, maintain good foot hygiene, trim your nails properly, and wear breathable footwear to support the healing process.

I hope this helps.

Thank you.

Hi doctor,

Thank you for the reply.

I doubt it is nail melanoma. So I am afraid of it.

Thank you.

Hi,

Welcome back to icliniq.com.

Cancer, including melanoma, is extremely rare at your age, so there is usually no need to worry. However, to provide you with the best possible guidance, I would like to ask a few more questions.

  1. Do you have any black or dark spots near or underneath your nails?
  2. Have you noticed any changes in the shape, size, or color of your nails?
  3. Any pain, swelling, or unusual symptoms?

To help me assess your condition more accurately, please consider uploading clear pictures of the affected nails. This will allow me to give you a more precise evaluation and determine if any further tests or examinations are needed. Rest assured, I am here to help and guide you with the right advice.

I hope this helps.

Please contact us again if you have further queries.

Thank you.
