I have suffered with concussion symptoms after having two whiplash injuries, causing multiple symptoms including severe head and neck pain, dizziness, and memory problems. I had trouble spelling words and often couldn’t remember my phone number and address. A friend of mine told me that I should see Dr. Charlie Simkovich. After trying other treatments without any success, I thought I would see Dr. Charlie. Now my mind feels clearer and I am able to remember simple things that I used to take for granted.
