I am only 22 years old, I do not have a brain tumor but am scared I might, I have recently have begun noticing confused type symptoms I have began experiencing. I tend to see things that arent there, and they are not hallucinations or anything like that, but I will confuse words and numbers, I can clearly see other things written down that might be a letter or two off but sometimes the word is completely different. And today while I was out buying things I picked up an item that I clearly saw the price saying 4.99$ and remember looking at it for a few minutes, but when I went to the check out counter and recieved my reciept it said the item was 37.00$ and I even walked over with the merchandiser and saw the price as $37.00 with no other signs around for the price I was seeing, it keeps happening, what is wrong with me? I am terrified.
