So, I hit my head when I was about 12 (20 now) while skiing and it was discovered after a trip to the ER that I had an arachnoid cyst in the posterior fossa of my brain (slight concussion at the time). I think its rather large, but exact details cannot be remembered. Had a bunch of MRI's and scans over the years and it was determined to be benign and not growing. I am supposed to be good and just look for symptoms relating to movement and balance and vision and things of that nature.
Im at university right now and have noticed a consistent issue when plotting graphs. Im mixing up the very fundamentals of math in my Calculus three course. I'll plot (3,4) as (4,3) as a very simple example. I've messed up so many problems and homeworks this way. Let me say that this issue never existed before the start of this year. It started a few weeks into this semester and has become a considerable issue. It seems to only be effecting my interpretation of the order of numbers in graphing and general writing. Grammatically I haven't noticed anything such as switching around letters just numbers, really strange.
I'm not at home so I can't see my doctor until I go home for thanksgiving, and I am really worried about this. I have been really stressed and slightly depressed, and this is compounding on top of it. I didn't think that because of it's location that the cyst would do anything in terms of my academics just body functions and sensations. So I dont know what to think.
