I am having the worst headache of my life. I have had it since Monday and have taken paracetomol, ibuprofen and mersyndol. I have also tried sinus medication. My head feels like it will explode, it feels like a lot of pressure, it is over my whole head, temples, base of the skull, and face. I can also hear whooshing sounds in my ear from my pulse. I normally have low blood pressure.
