Viral gastroenteritis is characterized by intense muscle aches (and this explains the leg pain he describes), muscle cramps and chills which precede nausea, abdominal pain, vomiting and/or diarrhea. Vomiting and diarrhea usually temporarily relieve the nausea and pain.
The vomit and diarrhea are usually non-bloody and the stool may lighten in color. People often feel fatigued and dehydrated because of the energy involved with clearing the infection from the body and losing fluid via vomiting and diarrhea. The symptoms begin 1-2 days after becoming infected with the virus and last 1-10 days, depending on which virus is involved.
The treatment of viral gastroenteritis includes rest, analgesics and re-hydration. Tylenol may be used to treat fever and muscle cramps. The replenishment of fluids with water, electrolyte drinks or oral rehydration solutions (sugar and electrolytes) is essential to prevent dehydration. When replacing fluids, it is important to replace volume and electrolytes such as sodium, chloride, hydrogen and potassium
