Understanding Chronic Headache and Migraine

Chronic headaches and migraines are complex neurological conditions that can significantly affect your quality of life.

What is Chronic Headache and Migraine?

Chronic headaches refer to headaches that occur at least 15 days per month for at least three consecutive months. These headaches can vary in intensity and duration and may be accompanied by symptoms such as sensitivity to light and sound, nausea, and difficulty concentrating.

Migraines are a specific type of headache characterized by severe throbbing pain, typically on one side of the head. Migraines often come with additional symptoms such as visual disturbances, nausea, vomiting, and sensitivity to light and sound. Some individuals may also experience aura, which involves sensory disturbances such as flashing lights or tingling sensations before the onset of the headache.

Symptoms of chronic headache and migraine

Symptoms of chronic headaches and migraines can vary widely from individual to individual and may include throbbing head pain, visual disturbances, dizziness, and cognitive impairment.

He has a background as a researcher, teacher and clinician and brings over 30 years of clinical experience to the Napa Pain Institute. Dr. Grigsby attended elementary and secondary school in his hometown of Knoxville, Tennessee, and received a Bachelor’s Degree in Biology and Economics from Brown University in Providence, Rhode Island. He formed an interest in Pain Management as a career while working at Boston Children’s Hospital in the Department of Orthopedic Surgery.

After graduating from Boston University Medical School in 1984, Dr. Grigsby trained in General Surgery, Anesthesiology, and Pain Management at the Mayo Clinic in Rochester, Minnesota. He was invited to join the Medical Staff and teach at the Mayo Medical School until moving to California in 1989. The Dean of the University of California at Davis Medical Center then invited Dr. Grigsby to establish their first Pain Management Center, where he served as Medical Director until 1992. Following his post at UC Davis, Dr. Grigsby established his private Pain Management practice in Napa, California.

Today, he and his staff of over 50 professionals consult with patients throughout Northern California and the western United States.  More recently, Dr Grigsby completed his Masters in Business Administration from Duke University’s Fuqua School of Business. He speaks nationally on topics such as non-operative treatment of spinal disorders, the safe use of medications for the treatment of pain, and the legal and regulatory issues relating to the proper treatment of patients with chronic illness.
