Hi,
Noted your history of chills, vomiting , nausea,
body ache and struggling with liquids.
All your symptoms are common to many diseases hence I would advise you the following in such a situation:
Consult your Primary Doctor for clinical evaluation, examination and investigations as per the clinical evaluation.
This may be due to viral infection,
gastritis or any other disease since there days have passed since you are suffering.
Till then you can a symptomatic treatment with a PPI like
Omeprazole.
Paracetamol after food.
Further medicines like
Domperidone for nausea and vomiting, antibiotics need a valid prescription of your Doctor, hence also needs to go to the Doctor.
Relevant investigations of blood, stool and urine will help further to get an exact cause and get treated accordingly.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
