I would like to discuss with anyone who has been experiencing idiopathic hypereosinophilia. My husband has had elevated eosinophils. He had a stroke last year at the age of 47. He has a history of undiagnosed skin rashes and Chron's disease. As long as he takes moderate doses of Prenisone his eosinophils stay down. We are contemplating a trip to Mayo, Rochester. Anyone experienced this?
