hi, im a med student 23, and i have been recently feeling vibration in my legs and arms. Also my eyes feel weird like i see things move or something fast like moves on the side but when i look nothing is there, also moving my head bothers me and i get nausea. i think it might be vertigo but im not sure. I also had stomach issues a week ago, and i have cold. But the vibration in my body and my eyes giving me headache and nausea is whats bothering me. And its really hard to study with these symptoms.
