unfortunately it seems like a majority of conditions chronic or not have flu like symptoms. a wild shot in the dark might be fibromyalgia because that causes random muscle aches. but there are a lot of things that could cause it from medical conditions down to nutrient deficiencies and lack of sleep.
what causes chronic flu like symptoms. i feel like i have the flu all of the time. chronic aches and pains feel feverish but do not have a fever. any ideas?
