Thanks for your query.
Noted the history of very fatigued during the day, exhaustion during the day, night sweats
regularly, stools are very pale, blood reports show high platelets, pain on left under the ribs, may be muscular....
As per the history you have noted, I can think of the following reasons:
There may be a medical disease or disorder like diabetes, hypothyroidism
or so and hence needs the following:
Get a clinical evaluation and examination done by your regular Doctor and get a reference for a Specialist as per the clinical picture and investigations.
I would also advise you the following:
Tests of blood: CBC., liver function tests to see for any hepatitis
and obstructive lesions in the gall bladder
and CT can of the whole abdomen .
Tests of stool and urine.
This will give the idea about the probable diagnosis and hence can plan for further management.
