Hi, I'm a 19-yr-old F and I've been having a crazy array of symptoms for months that's caused me so much health anxiety (pain, burning, twitching, nausea, tingling, weakness, headaches, pressure on my forehead, trouble getting out words, trouble balancing, blurry vision, brain fog, sensitive sight, etc), and last night when I went to the ER they performed a CT and found a cyst near the back of my brain. I'm getting an MRI soon, but I'm really freaked out about it because they said it was big and likely has been there for a long time....and I know some can develop in the womb but I haven't noticed any of these symptoms until this year -- especially in the past weeks. I know a lot of them are harmless and can be drained but they didn't tell me much about it ...
So my general question is what information you can tell me about brain cysts given my details? I've read that if not developed at birth, they're a cause of meningitis, head injury, or tumors, and along with falling on my head as a toddler I smacked my head during tubing this summer, but no concussion or anything... The MRI will surely tell me more but is there any information you'd have that could ease my mind or at least inform me a little better? I'm not sure what to think of this, and I'm just trying to stay positive and not focus on the forehead pressure or forgetting what's going on every few minutes (symptoms bothering me most right now). And with what symptoms should I seek immediate help, if any? The ER told me to get it checked out but that I didn't need to stay overnight. Thanks so much!
(Also, if I should have posted this in neurology please let me know and I'll repost there:)
