hello
i would first and foremost suggest you meet a live doctor
i am not sure your condition should be tackled by distance medicine
however if you have some delays in getting to a doctor
i would suggest you at least get an
mri of the brain
i would like to rule an intracranial lesion
having said that i would like to tell you why i responded in this fashion
your symptoms may simply be explained by fluid and
electrolyte imbalance this could be secondary to your tummy condition
in which case plenty of fluids and electrolytes will help you
however vision disorders and sudden sweats (probably an episode of
low bp) warrants getting an mri to rule out intracranial pathology, and in which case you should meet a live dr as soon as possible
finally you should get your sugars- fasting and pp- tested. there is a possibilty that you have undetected diabetes
i am sorry i could not give you a direct answer
please let me know the results of the tests suggested
and maybe i can help you further
do consider my advice of meeting a live dr, preferably a
neurologist at the earliest
best of luck
