6. Flu-like symptoms
Sweet syndrome is known to appear a few days or weeks after having a fever, which is in itself another common symptom of an immune system actively fighting a condition or infection in your body. Sometimes, the fever could be caused by the flu of varying severity, and after a few days, you feel like the flu is back, or at least has never gone away. Some of these flu-like symptoms include tiredness, body ache and congestion or soar throat.
These symptoms might not be relieved by traditional flu medication and are in most cases a manifestation of your immune system battling against a foreign element, germs inside your body or even a tumor. In some pregnant women, the body might even develop a Sweet syndrome with flu-like symptoms if the body itself has a hard time adapting to the new situation. Flu-like symptoms can be an indicator of a bigger problem.
