Anyone ever get a headache that is persistent in one section of the head. I have had a dull aching pain in the back left of my head for a four weeks now and it is so persistent. NOt really there in the morning and then comes out during the day, every day. There is also this malaise feeling or lightheadedness that accompanies it which is no fun. Had a cat scan done which came back negative and have had a few sinus issues on the left side of my head as well where the CT revealed that there was a polyp on my left sinus. But the headache is in the back and Im not sure if its something I am manifesting or if it is legitimate. Plan on going to a nuerologist at some point but wanted to see if anyone else has ever experienced this.
