It could be something as simple as working out too hard and/or not having enough carbs in your system, but we'd have to know more about what's going on. How fast you are riding, how far you go before it happens, how hard you feel like you're working out.
Having said that, however, the symptoms are troubling, and I think you should definitely see a doctor before you ride more.
