*NOT A STROKE*---- need opinions

After court I went by my parents house yesterday and my dad said he needed to take my mom to the emergency room. I asked what was going on, and he said she's shaking and kept calling him by my brother's name. I went inside and saw her on the bed uncontroably shaking. My dad asked me to stand by the bed while he got the car ready, and I looked her in the eyes and asked if it was her back problems and she didn't say anything. A minute later she finally screamed out "PRESSURE........HEAD" then said "I love you" and "take care of everyone" and "I'm so tired" before my dad came back in. He tried to lift her to get into the car but it wasn't happening. I asked if we need to call an ambulance (apparently this had been on/off since Sunday and the local hospital released her with Tylenol 🤦🏼‍♀️) and they came. They took her to a hospital 30 minutes away because they thought she was having a stroke (something my uncle died from in 2012, and something I saw her already go through in 2001) and our local hospital "isn't a stroke treatment hospital" CLEARLY. Moses Cone wasn't any better. They did scans and said it wasn't a stroke. They gave her pain medicine but because she couldn't fully say her pain on 1-10, they didn't give her any more. She thought the month was September and she thought she was 4 years older than what she really is. Still, the only thing she was able to say was "pressure ..... head" in a very shakey voice. The nurse said "looks like you're just having a bad headache!". Like why do these people think it's a headache?!? Has ANYONE experienced this personally, or medically? She's 66 with a ton of health problems, she thinks it's September and her whole body won't stop shaking while she's moaning about head pressure. Yea it's good this isn't a stroke, but clearly this is not a headache. Any suggestions PLEASE let me know cause we're at a loss. I'm hoping my brother took her to a better hospital like we had planned on.
