What Causes Nausea, Excessive Thirst, Headaches And Upper Stomach And Back Pain?
They all look to be related.
Thanks for your query and an elucidate history.
After reading your symptoms carefully , they all look to be related.
-Nausea, thirst, headache stomach ache, back ache which is not constant, fever, tiredness along with thick tongue and swollen glands around the neck.
These are more suggested of flu- viral infection.
I would advise you to take Panadol at 6 hourly interval .
Consult a Doctor to see if the swollen glands around the neck were the primary cause for the other symptoms you developed or the effect of flu.
This is because if the glands came first and then the other symptoms, you probably will be started on antibiotics and other anti-inflammatory medicines like Ibuprofen or so.
Bed-rest helps a lot for early recovery and plenty of oral fluids (which you already are taking).
I hope this answers your query, please feel free to ask for more if you need to.
