Migraines Resulting from Qigong Practice

Last year I started a Qigong practice. This type of Qigong was created just three years ago. The purpose of the method, which I recently found out, is to build a lot of Qi quickly. When I started to practice using this method I felt great. I had suffered from chronic pain for decades. However, after about three months of daily practice I started to experience migraine headaches. I have never had a migraine in my life and I didn’t know what was happening. I was also experiencing nausea, vomiting, dizziness and light sensitivity. The symptoms got so bad that I could no longer practice standing up. My life changed dramatically. Besides going to work for six hours a day, I live completely in the dark. I don’t watch TV, use the computer or go outside due to the light sensitivity. I have been to acupuncturists, chiropractors, and neurologists. I contacted the teacher who created the Qigong method and was told that my headaches were not a result of the practice but a coincidence. I was also told not to stop practicing the Qigong method and that my migraines would go away. Unfortunately, they have not gone away. I am desperately trying to find relief. Can anyone help me to move this Qi? Any advice would be greatly appreciated.
