Are cavernous malformations brain tumors? I have been diagnosed with having 10-12 throughout my brain, with one 2cm one in my brain stem(pons region). Three have shown evidence of bleeding in the past couple of months(including brain stem). I'm so confused about my prognosis and future, that I'm feeling terribly anxious and depressed. My right arm and leg were experiencing deficits, but have improved...but I'm now experiencing some headaches and neck pain...what can I do? What medications work for this, and am I a "walking time bomb" because of all of these things in my brain??? I need some answers...thanks
