Went in today with major pain in my neck and right shoulder (going on 4 weeks). I have been to Dr Harrington before but years ago. I called and he saw me that same day. He laid me on the table, checked out my body alighnment. My axis has always been a little off. Nothing new to me. The pain I was experiencing though was excruciating. Dr Harrington used a little machine on my neck just behind my ear and done. No neck twisting and cracking. Pain free experience. That same day my neck and shoulder feel great. I don't know what he does but it's awesome. I would recommend him to anyone.
