My husband is 37yrs old.He has been having several health problems since a very age of 6. He was diagnosed with rheumantic chorea & was treated accordingly,was on Penidure injections till his 25th year. His absolute eosinophil count has been always very high. He has allergic bronchitis & generally has dry skin all over the body.Also,he has difficulty in sleeping.Now suddenly since 2 week he was complaining of lightheadedness. When we did consult a physician, we found out he has low BP, it was 70/90. What could be the reason? What steps to be taken?
