Hello,
Reading your query and the results of the blood tests, I presume that the percentage of
eosinophil count is 10% that has several causes.
The commonest cause in tropical countries is parasite infections, and
antiparasitic treatment is recommended after stool culture studies. This is a must before going through unnecessary tests or treatments.
If the eosinophil count remains high and
sneezing and rhinoconjuncitivitis symptoms persist, it would sugest allergies as the underlying cause.
Pollen allergy, smoke (industrial) are major factors that needs high dose antihistamines and
steroid nasal sprays. The duration of treatment will depend on the trigger (i.e., seasonal vs perennial [all year around]).
There are several other causes but infections, allergies and rarely autoimmune diseases are causes of raised eosinophil counts. I also hope you have recognised red flags such as significant loss in weight and appetite that should be taken more seriously.
I hope this was useful.
Best Wishes.
