I too have a brain tumor. And Migraines led me to an MRI that found the tumor. Tumors are not that common and most people with migraines do not find tumors. I have a low grade tectal glioma in my brainstem. It is in-operable and is slow growing. It is not cancer which I am very thankful for. But I have headaches/Migraines everday. I had to leave my job and we are in the process of selling our house.
Some doctors say the tumor causes the headaches/migraines and some say they don't. I have tried many different preventative medicines and nothing has worked so far. Imitrex does work to get rid of the bad migrianes but I can only take it once in a while or it stops working.
I may wake up in pain every day but I am thankful that I wake up and I can kiss my three year old son every day. Most of the brainstem tumors are fatal so I consider myself very lucky.
I want to wish you the best of luck in your surgery and let you know that my thoughts are with you and I know you will do well.
I will check back too see how you are doing.
From one brain tumor to another.
