Hi grco,
I am very concerned about the dizzy spells and falls. That can be a very serious sign of something wrong. It may also be something less serious, like Virtigo; but, that being said, I would suggest he see a doctor right away. Panic/anxiety can get worse if not treated with medication. There are some medications that will help and your doctor can guide you to what would be best for him. If you look on Google under Meningitis financial help, there will be some ideas to look into for financial assistance.
I am not a doctor, but I feel he needs to be seen ASAP. Best Wishes, CharlieJane
