I have a sister in law that has suffered from headaches for two years. She says it start in the morning and gets worse by night. She has had scans and xrays and only thing they found was a degenerated disc between 4 and 5 in her neck. She saw a spinal surgeon and he said it was not the cause of her headaches. He sent her to a pain management doctor who did injection in her scalp which worked once but nothing after that. I think she is having tension headaches and my question is can you suggest a different type of doctor or something else she can do.
