I was wondering if your a smoker(cigarettes) My 16 year old was suffering from headaches constantly at home for several months (living with her mother) and was given several different meds but nothing seemed to work. She went through cat scans and spinal taps which all came up negative. One day when she was staying by my house she realized that she never suffered from any headaches there. What we found to be causing her headaches was her mother smoking in the house. My home is smoke free. I confronted her mother and she stopped smoking inside the house and my daughters headaches subsided.
