The medicine for scarring is covered by insurance.... (I'm so embarrassed!) Please answer ㅠㅠ

There's something I'm curious about~~ It's been about a month and a half since I had my nose surgery~ I heard that Lizaven or Treno are good medicines to prevent scarring... Someone told me that I can get Treno or Lizaven at a family medicine clinic or internal medicine clinic and get a prescription cheaply with insurance, so I'm thinking of going to an internal medicine doctor. ... I was planning to take 2 months' worth, but I told the doctor... I went to the internal medicine doctor and they said I had allergic rhinitis. I was taking Treno, but I lost the medicine and they said I should go to a nearby internal medicine doctor. Or what should I say... ㅠㅠ
