In general, the question is not about pregnancy and childbirth, but everyone has children, so I'm asking... Has anyone encountered SYNDROM MARSHAL in a child aged 2.8? It's my assumption for the doctor, we will only go to another city on Tuesday, So, I'll briefly describe it: monthly temperature and swollen lymph nodes for 1.5 years, many times treated, hospitalized but useless. And then I stumbled upon this SYNDROM on the internet based on descriptions similar to what is generally known. If anyone knows or has encountered it, please write back.
