I actually was diagnosed with a benign 3.5 centimeter bone tumor in the frontal bone 4 years ago, it has been followed with regular scans and hasn't changed since it was discovered. Usually, I have a constant moderate dull pressure deep behind my forehead...it doesn't throb or get worse with activity. My doc says that it's pretty clear the cause of my symptoms but I've turned down the surgery option. However, my question is about this, here lately I seem to have a worse, throbbing headache that lingers on for sometimes days at a time. Sometimes my head feels peculiar, like a mild electric buzzing inside and increasing to this throbbing pain. Quite often, I wake up in the morning, or even get woken up early by terrible throbbing pain in my head, and when I get out of bed it immediately improves by 50% but does certainly not go away, it will linger for many hours or even days. Other times, if I just lay down for a nap, and especially if I lay on my stomach, or bend over forward to too long, I develop this throbbing headache, and it does not go away when I stand back up, but does improve slightly when I stand up. My last dilated eye exam, 3 months ago, was normal, and last month, the doctor looked in my eyes (non dilated) and both events were normal exams. Could I have a mildly elevated CSF pressure causing this, even with a normal eye exam? Do you think this is not likely? What can this be, that my headache is changing for the worse, but my tumor is not growing and I don't have papiladema?
