My Girlfriend Had A Seizure Whilst Giving Plasma. She Said

My girlfriend had a seizure whilst giving plasma. She said it lasted less than a minute and felt like a nap. The nurse in charge if her said she jerked up, down and then stayed down appearing to "Flat line" for several seconds before coming to. They gave her gatorade, and crackers and had her lie down for 15 minutes before letting her leave. It's been almost two hours and she feels very ill, having already taken three generic tylonal in the last hour for a tooth ache. What else can I do from home? A hospital is not an option right now due to financial issues. Her arm hurts and she feels very light headed. Advice?
