My husband is going through crazy experience that no doctor can pin point. He gets itchy all over. went to the allergy specialist had blood work done no solution. he is taking Allegra everyday. it help some but cure. He gets incidents that make him hard of breathing. not walking or running. He went to the Lung specialist and his lungs are healthy. His throat get dry and sore and his breathing goes in a spasm of hard of breathing. It is a puzzle that no body can pin point. it is not panic attack. he been checked for that too. any help is great!
