If the answer is more than once or twice a month then it is far too many.
Weekly headaches are not normal and suggest an underlying problem. Very often these are tension-type headaches and they originate from postural issues resulting in tight and stiff muscles in the neck and shoulders.
Spending hours a day driving, sitting at a desk, studying, or working at a computer are all common causes of postural stress and tension.In order to reduce your headaches these conditions need to be addressed, and any built up tension or spasm needs to be treated. Chiropractic care takes both of these aspects into account, and offers a high rate of success in improving and preventing tension headaches. Don't live on painkillers that simply mask the symptoms, find the root cause and resolve it.
