Thank you for the additional information.
Stress can make almost every headache syndrome worse, so the details about the headache and the associated symptoms help to clarify the type of headache syndrome.
This sounds most likely to be muscle contraction headaches. Muscle contraction headaches are the most common type of recurrent headaches and are frequently worse with stress. In fact, these headaches are historically referred to as tension headaches, although the current preferred term is muscle contraction headaches.
There is no treatment that will permanently eliminate muscle contraction headaches. However, there are several options for treatment of muscle contraction headaches. When the headaches are infrequent, then the usual approach would be various medicines to help ease the pain. Any of the over the counter pain medicine are fine to take, but the anti-inflammatory medicines, such as ibuprofen or naproxen, are usually more effective. It also may help to perform massage or ice massage over the area of pain. If these interventions are not sufficient to ease the pain, then there are many other medicines available by prescription, although it would be necessary to see your doctor.
When someone is having more frequent headaches, then there are also several treatments that can help to prevent the headaches. The most commonly used are certain antidepressants, such as amitriptyline or duloxetine. Muscle relaxers, such as Flexeril, also may be useful Any intervention that helps to ease stress can also help prevent the headaches, such as getting regular exercise, yoga, self-relaxation techniques, etc.
