Hi: my thoughts are with you. Sounds like what I went through 2+ years ago. I had a silent seizure, the hospital did an MRI and found a golfball sized benign tumor in my front left forehead. Said it may have been slowly growing for 20 years. Who knew? I thought I was just depressed. I went from barely walking or talking to close to normal within a few days. But the seizure medications I take now have really messed up my energy and balance, and altogether I’ve “missed” a few years of my life. I now also have pretty severe neuropathy, which has really curtailed my life. I’ve had so many neurological tests, nerve tests, cardio tests, etc. but all the results are normal. Does it have anything to do with the brain tumor? Again, who knows? Keep taking any tests they suggest, going for your MRIs, and don’t ever give up! I’m rooting for you.
