After the fever has been reduced, there is pain all over the body and some relief measures are taken, which mainly depends on the cause. The more common causes in clinical practice are acute upper respiratory tract infection and bronchitis. At this time, you should take proper bed rest to avoid getting cold again, recover your strength and improve your physical fitness. You can take analgesic and anti-inflammatory drugs, such as ibuprofen, acetaminophen, diclofenac sodium, and test your blood count, and if the inflammatory reaction still exists, you can take anti-inflammatory treatment. If it is caused by bacterial infection, antibiotics such as penicillin, amoxicillin and cefoperazone should be given; if it is caused by viral infection, antiviral treatment such as ribavirin, oseltamivir and cytarabine should be given, which can relieve pain.
