Dealing with Brain Tumors and Fainting Episodes

So I have tumors but the doctors keep fighting about what it is. I have two saying it's brain tumors, slow growing. I have one saying it's air bubbles around my blood vessels in my brain, I have another saying it's cysts in my brain so I don't have much information on what exactly I have. Anyways, I've been having bad fainting episodes and I don't know what exactly is causing it. I had a very bad one a couple weeks ago to where my entire right side went completely numb with static in my right wrist that followed the thumbing of my headache on my right side. I went to the ER and the doctor thought I was having seizures that acted like a stroke based on where my tumors/cysts/air/whatever was located which is on my left lobe near that memory part. basically near my left ear a bit behind it but not quite. Has anyone dealt with any of this before? If so, what did you go through? What procedures were put upon you?
