I have had a headache that goes away with OTC for about 7 weeks. I haven’t been taking too many a day but on a daily basis I have 400mg of advil OR excedrin. This does relieve my headache until the next day when it comes back. In addition to the headache my head feels really heavy, sometimes the back of my head is tender or sometimes its behind the ears. I have see my PCP with no real advice or solution other than stress managment. I have decided to see a neurologist but while I wait I wanted to see if anyone else has experienced this.
