Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that the symptoms of chills, fever, body aches, diarrhea and fever can be due to causes like
Stomach flu or
Viral Gastroenteritis, food poisoning,
parasitic infection or Giardiasis etc..
A proper clinical evaluation and investigations like Blood tests, stool culture etc can help in diagnosis and treatment can be done accordingly..
You should consult an Infectious Medicine Specialist and get evaluated..
You can be advised Antibiotics if there is bacterial infection while
antiparasitic mediation like
Albendazole can be given for Parasitic infestation..
Fluid replacement therapy, Loperamide for reducing loose motions and Tylenol can be given for fever and body aches..
Take a semi solid food with more of cereals, banana, rice, Yoghurt in diet..
Hope this information helps..
Thanks and regards.
