Over the past week or so, I've been having weird headaches that have been centered under the eyes and around the nasal cavity. I've also had some slight pains in the back of my head. Other than these headaches, I've also noticed something extremely odd in regards to my reading patterns. I'm currently studying to take a big test next week intensely and have noticed that I've started seeing words that aren't even there and reading words wrong. For example..I will read "remember" as "revered" and see imaginary "and's" after a comma when they aren't present. All of these reading errors just seem to be momentary slips and don't happen on a continuous basis, but occur with decent frequency. I'm so worried that I have some type of brain tumor and that this symptom is one of the initial signs! I've always been a big reader and this is absolutely frightening.
