Mini-update: My mother seems to be OK, though the neurologist is sending her for an MRI just in case, and has asked her to start taking low-dose aspirin.
DH has had his MRI and 24-hour EEG; his follow-up appointment with the neurologist is tomorrow. His mood has improved, so I think he's slowly adjusting to the Keppra, but he is still pretty sleepy. We are hoping we'll have SOME answers tomorrow, but the likely outcome is that we WON'T know anything more. There in lies the rub. Or it could be something horrible -- like a brain tumor. I don't know. We are living minute to minute right now. Time flows differently when someone is ill (or potentially ill). Days drip drip drip by, like water from a partially-open faucet.
I am feeling pretty burnt right now; like I am running on fumes. But M. is a child and I have an obligation to her to keep moving even when it's the last thing I want to do. Hopefully relief is around the corner. We'll see.
Thank you again, to new friends and old, and much love. I hope I can repay the favor if/when you need it. <3
