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.
