Note

• If you do not see the coincidence of these wildly unrelated diseases, you do not believe this is really happen
• And now, the main question is what is the common ring of these disease
• This could be nothing except a Miasm named HSV-1 and HSV-2
• I suggest Central sensitization syndrome as the main common entity
