Hi,
With the history of pain in the upper abdomen, nausea, shaky hands, fever and bad taste in the mouth you need to see a Doctor.
All these symptoms may be due to one of the following reasons:
-Traveler's
diarrhea.
-
Hepatitis.
-Colitis.
Hence, there is a need for clinical evaluation, an actual physical examination and relevant investigations like:
-Blood for CBC, liver functions and as needed.
-Tests of stool and urine.
-Other investigations as per the clinical presentation found by the Doctor.
All these things will lead to a correct diagnosis so that an appropriate management can be done as you are traveling.
Till then take oral rehydration solution, symptomatic treatment like
Paracetamol for fever,
Domperidone and a PPI like
Omeprazole for nausea.
Take plenty of oral fluids. Make sure to stabilize the condition before you travel.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon
