Can I put any cream on the lesions? I am currently using lanolin, but is there something better? Is it okay with PMB?

Yes, you can apply any cream that helps to relieve the lesions. Lanolin can be effective, but you may also want to consider using a fragrance-free cream or lotion like Base Glaxal or Aveeno. If there is no improvement after 10 days or if the condition worsens significantly, it would be a good idea to consult a doctor as a precaution. Feel free to reach out if you have any other questions!
