I have had a headache non-stop for about a month now. I have been treated for sinusitis to no avail. Nothing changed the least bit. It is so bad that Tylenol 3 and Percaset don't even touch it. I frequently have nausea, dizziness, but no light sensitivity or fever. It is so bad I can hardly stand it. The doctor has me going in to the hospital in 3 days for a CT Scan. If you have anything to reply about please do. I have never had a problem with headaches before and nothing has changed in my life that I can think of to cause them. Thank you.
