My husband has a family history of blood cots in the brain. It has killed two of his close male family members. He also gets cluster headaches. I am not well versed in any medical knowledge. He said it has something to do with his hypothalamus swelling and causing something to secrete. He started getting injections today and will be getting them 2 to 3 times a week. I am very scared, obviously. He has worked in hospitals his whole life, and has tried to explain to me what is going on, but is speaking well over my head. Can you please direct me to a brain clots for dummies that I can read up. He wants to do this by himself, because it is his nature. But I can not handle not being knowledgeable on the subject. Thank you for you time, Concerned wife
