My daughter is currently receiving treatments at MMTR in Guelph for post-concussion syndrome. First 3 treatments she felt worse, not better, but by the 5th treatment, her nausea was almost completely gone. What a relief that was for her. She continues to get better but it may take some time depending on the symptoms. Her headaches are better, she has more energy, but we are still working on the noise and light sensitivity, and concentration problems. We see lots of progress. MMTR really works!
