Dave the thing is I went to the doctor 3 times, and he kept saying the same thing. Hell in the beginning he didn't even see the cyst at all, it wasn't until the radiologist report said I had a cyst. The doctor is a neurosurgeon by the way and he says the cyst is too small (5x5 mm) to be causing any headaches. I also saw a neurologist and he said the same thing. I am planning on seeing a neurosurgeon in Israel. But as you said, at least he has me scheduled for a follow up MRI. He said to keep it under surveillance every year. But I might get it checked in another four months (which is six months from the date of discovery).
