Hello,
Thank you for posting your query to HCM.
Yes, it most probably is a
thrush infection. The fact that it came after the use of an antibiotic, and the place where it has developed indicates factors that have helped the fungal grow.
Try to keep it as dry as possible. I usually suggest to my patients to take
Canesten 2% cream, to use twice/day for 5 days. If it is used with a thick layer, spread to cover about 2 cm over and outside the borders of the crusts, it will be enough to clean the infection.
If it doesn't get better, or is getting worse, consider to have it checked by your local doctor. Its very low possibility to be something else, but sometimes is better to have a look.
If you have other questions, feel free to ask. I would be happy to answer.
Take care.
Dr. Klarida Papaqako.
