Hello, pityriasis rosea is a common inflammatory skin disease, which usually occurs in the trunk and proximal limbs of different sizes, with an indefinite number of rose spots and pityriasis scales. It is self-limited and usually lasts for 6-8 weeks.

Suggestion:

Antihistamine drugs such as chlorpheniramine, cyproheptadine, Terfenadine, Kominin, etc. can be used appropriately, and vitamin C can also be used. Local calamine lotion can be used externally, and it is best to go to the gym after recovery. I wish you a speedy recovery!
