Fever, body aches, fatigue and rashes are common symptoms of illness, although they do not always occur concurrently. Fever alone can cause muscle aches and fatigue as the body tries to heal itself and reduce inflammation. Usually you can treat these symptoms with fluids, rest and a few days off your regular schedule. However, if your symptoms don't resolve or recur with regularity, seek medical advice.
Lupus Erythematosus
Lupus erythematosus is an autoimmune disorder that causes the body's immune system to attack healthy organs and tissue. It occurs most often in women, although men get it, too. Symptoms are often based on the organs attacked by the immune system, and often include fever, fatigue and body aches. People with lupus also often develop a butterfly-shaped red rash over the face. The rash usually appears or deepens in color when exposed to sunlight, according to MayoClinic.com.
Parvovirus Infection
A parvovirus infection, also called fifth disease, is a common childhood ailment that includes a facial rash, fever and fatigue as symptoms. Additional symptoms include sore throat and itching. The rash on the face is usually on both cheeks and bright red. Adults can also get the parvovirus, although they rarely get the rash, reports MayoClinic.com. Adults will suffer more joint pain. The infection is usually mild and resolves in a few days, although it can be dangerous for pregnant women as it can cause health complications with the fetus.
Erythema Multiforme
Erythema multiforme is a rash that sometimes occurs on the face, but can also occur elsewhere, including the soles of the feet or the lips. The rash sometimes appears as a symptom of another infection such as strep throat -- which would occur with the rash, a fever, fatigue and muscle aches. In the case of a bacterial infection, antibiotics can clear the rash and the other symptoms. However, erythema multiforme can also occur independently as a result of the herpes simplex virus. In that case, there may be recurrences throughout the year without accompanying symptoms, according to The Merck Manuals Online Medical Library.
