It sounds like you are having severe headaches. Let us know how things go!
My toes started getting a little numb about 6 months ago. Just the middle 2 on the left foot. In the meantime twice in 6 months something strange happened. I awoke in the middle of the night with a pain in the top of my head like something hitting me real hard. Only the pain was on the inside of my head. It hurt so bad that it woke me up both times. The pain immediately went away but it scared me. About a month ago I was sitting with my legs crossed and my foot went to sleep. It took about 10 minutes for it to get back to normal. Then the numbness came right and went all the way up to my knee. There was throbbing in my leg and feet for about 2 days but no pain; just throbbing and numbness. It never got back to normal. Now the bottom of my foot is numb and all but my big toe. I went to a neurologist and he recommended a nerve shock test and a MRI. I had both tests the same day. The doctor found a pinched nerve behind my knee so I assumed the MRI would come out find. The next day I found out I have a 3cm meningionma on the right side of my brain. I have also had memory problems for years. So I don't know whether or not these are symptoms of the tumor but the surgeon says it should come out so I don't have seizures.
Are you having symptoms? Usually symptoms, location and your health dictate the removal.
It can depend on things we don't have here like your total medical history... why not get another opinion and talk to that doctor as well.
