I have been suffering from a gastro bug which has them turned into just a fever with muscles aches and general malaize, the fever broke a couple of days ago and have ben left feeling completely debilitated, with no appetite, and mouth ulcers?

Viral Fatigue: Fatigue, muscle aches, and low grade fever are the bodies attempt to limit our activity, encourage rest and direct all its energies to the battle at hand. Consider how a military campaign works. Troops defend against an enemy but must be supplied, reinforced and given rest to continue fighting. The body works in a similar way. Work with your body, not against it. A tincture of time is needed.

GI issues: In today’s times you must consider the possibility that you had coved 19 as diarrhea and a flu like syndrome can be the presentation. Did you ever have fever or cough? Please self quarantine for 14 days and consult with your doctor by phone. The mouth ulcers are probably just part of the GI inflammation.
