I'm glad you no longer think it's a stroke, and I'm pleased to hear you have a doctor's appointment.

It might be worth asking about getting a blood test to check some basic vitamin levels
(like Vit B) ......... maybe electrolytes too as that way you would also get your Calcium and your Magnesium levels checked.

Good luck with your appointment..... don't forget to come back and tell us how you get on.
