there are several causes of blood eosinophilia,
2- allergic disease (dermatitis, rhinitis...)
3- stool parasite
5-hypereosinophilic syndrome, which involve at least two organs with eosinophils (lungs, nervous system, heart,.....)
6-bone marrow problem (lymphoma....)
7- and finally drug allergies.
so your physician should screen for the presence of any.
as for the sedimentation rate, in female it is usually equal to half the age+10 so for you it should be 25. and it is a non specific test which is also slightly prolonged if someone has an anemia, fever, viral infection. for more serious disease such as bacterial infection its higher than that, or rheumatological disease which is very high.
