I have contusion and concussion. I know when inflammation is coming on in my head or that it feels like it. I was told to take only "Tylenol" for inflammation of the head and Ibuprofen for Inflammation in the body, as told by my physician. And in minutes it seems to improve. and I know that after physical work such as lifting or ironing, lately I get nausea and dizziness as the result. Be careful.
Try taking Excedrin Tension Headache, since you've only been taking aspirin, this should help. You can also speak with a pharmacist, although it is Memorial Day.
