Welcome to Neuro Talk. My neighbor just finished two weeks in a hospital learning bio feedback. Her headaches are over 8 years, and she was on fentanal. It is amazing what this did for her. Her pain has been reduced from an 8 to a 3, in just a few weeks. Detox went well, and she has hope that this type of therapy continues to help. Just an idea, as I know from my neighbors experience how bad those headaches can be. Again welcome, and we will be here to support you. ginnie
