[|Human|] I have a B12 deficiency and have had 2 MRI s. They say I have a 4mm tumor which is benign in my brain and has not grown. Nothing to worry about, however, I also have like vertigo, when I position my head. Also I feel like I m out of balance, my eyes are jumpy, everyone says I m fine. What could this be? I also have twitching at times on my left thumb and lip
[|AI|]  Hello, I would like to know the exact location of tumor in your MRI brain. This will give me an idea about nature of your symptoms and I will be able to correlate them to your MRI brain. Jump to eye, loss of balance, and vertigo is suggestive of a problem in cerebellum or its connecting tracts. But the twitching in left thumb and the lip may be due to a lesion in right cerebral hemisphere. You can get symptomatic treatment for these symptoms from your doctor after a careful review of your detailed history, physical examination and MRI brain. Hope I have answered your query. Let me know if I can assist you further.
