question: A week ago I had a sudden attack of vertigo , (so violent that it almost caused me to fall), which lasted only a minute but left me weak and dizzy for an entire day. The next day I felt better but still prone to dizziness . Now, a week later, I m mostly fine but yesterday I experienced a momentary dizziness while having lunch outdoors. This morning, I awoke with a sharp pain in my right upper shoulder . The pain does not seem to be traveling down my arm but I m having difficulty moving my arm without pain.
