What is Pityriasis Rosea and how does it affect MS?

Pityriasis rosea is a common skin condition characterized by the appearance of a large, scaly rash on the body. It typically starts with a single, oval-shaped patch called the ‘Herald patch,’ followed by smaller patches spread across the torso, arms, and legs.
While the exact cause of pityriasis rosea is unknown, it is believed to be triggered by a viral infection.

Although the link is not yet fully understood, researchers suggest that MS and Pityriasis rosea conditions may share a common underlying immune system dysfunction.
Both MS and Pityriasis rosea involve an abnormal immune response.
In MS, the immune system mistakenly attacks the protective covering of nerve fibers in the central nervous system, causing neurological symptoms.
Pityriasis rosea, on the other hand, is believed to occur when the immune system reacts excessively to a viral infection, resulting in the characteristic rash.
