I tested positive for RSV 2 weeks ago. I have had coughing like a child with the croup, severe congestion, low grade fevers with sweating, muscle aches and severe weakness. After the first week it felt like I was recovering somewhat, but then I seemed to relapse once again. I have NEVER experienced any other virus like this except for the flu (I am 56 years old). It is far cry from just a severe head cold!! The viral aches and weakness make you think you are coming down with the flu. Dec 22, 2019
