I had an MRI scan and have been told I have a 6mm nodule on my brain (can't remember exact location).  I had the MRI following a collapse in August when I experienced stroke like symptoms on the right side of my body.

Since August, I have been exhausted, depressed, poor apetite had tremors and tingling intermittently on the right side.  Can the nodule cause these symptoms? What does this all mean?
