Milwinny, I am so sorry to hear that you were injured and that you are still not healed. I too am recuperating from a blow to the head; mine is definitely a concussion. I've done a lot of reading about concussion and I've learned that symptoms can surface months after the event. The fact that your injury hasn't healed yet says something. Heads and brains can be very slow to heal. I wish you well. Stay in touch.
