I had been told by several other doctors after a few falls and one led to a large absess being removed from my ankle. I have been experienceing dizzines, tremors and severe headaches. My Nuerologist sent me for a CT scan and an MRI of my brain and I'm scared about the spot they found on my brain. Should I tell the doctor about my brother and is there further testing to find out what the spot on my brain is?`
