Headaches and coughing don't go well together. I've been coughing for the past two weeks now and I've had this incessant headache for about a week. So everytime I cough I feel like someone just punched me in the head. Cough...ow...cough...ow...cough...ow. I try to surpress my coughs but it's hard...one time I felt a cough coming on so I took a big gulp of water. Yea, I ended up spraying the water all over myself. Yuck.
