I'm in the group with co-morbidities, age + MS. I just got the flu yesterday and had a 102 fever and plenty of aches and pains. But I'm better today, just a low fever of 99. It seemed like any other flu I've ever had with aches and pains randomly firing off around my body. I find that fascinating and interesting and like other times I've had the flu, almost enjoyable. It's not every day I get to feel things like this with all my nerve damage. I didn't take Tylenol because it's bad for the immune system, but I took some other stuff to shorten the duration, I guess it worked.
