question: Hi doctor,Seven months ago, I had a serious head injury. That time, I was left with a small hole in the skull after extradural hematoma evacuation. Then, I had no discomfort in the head. Now, I have terrible tension around the back of the head and dull pressure and pain next to the hole. I feel hyperemotional, frightened, extreme anxiety and jaw clenching. I had none of these for seven months post surgery. Is it safe to live with this hole? What is underneath it? Will it affect my life? Why am I getting sudden extreme head tension and dull aches? From yesterday, I am taking beta blockers for stress and tension. My neurologist said that I am free from brain damage. But, I need more advice.
