A frequent and overlooked cause of headaches is the malfunction of spinal bones in the neck and upper back. When bones of he spine lose their normal position or motion, sensitive nerves and blood vessels to the head can be affected. When spinal nerves and related tissues are stretched or irritated, they can produce throbbing headaches. Aspirin and medications may cover up these warning signs, but do not correct the underlying structural cause.
Many people experience correction and relief through chiropractic care.
