... the tumor so they can operate. I am also a migraine sufferer. I take Imitrex for them but can't take it every day. I was given a shot of Neulasta a week ago and have had 4 migraines this week and I can hear a whoosing sound (Like blood pumping). Does anyone know if there is something I can take to constrict the blood vessels. I have taken coffee and it helps but can't do that at night. Have slept only 5 hrs. in 2 nights thank you, Beverly
