I Have Been Experiencing A "tingling" Feeling In The Front

I have been experiencing a "tingling" feeling in the front of my head (left side) and sometimes goes down to my left cheek. I went to the ER a couple weeks ago (wanted to make sure I wasn't having a stroke). At the ER my blood pressure was good (always is), EKG was fine, CT Scan normal and the ER physician consulted over the phone with a neurologist. They sent me home, but instructed me to see my regular MD, which I did right away. She ordered the MRI and I just received the following results "Left posterior temporal developmental venous anomaly. Nonspecific punctate T2 bright foci, otherwise negative exam. There is no abnormal enhancement." Can you please tell me what this means? Thank you for your help.
