What Causes Severe Body Vibration And Dizziness?

Just rubbed counterpain - an equivalent to bengay - all over my body excluding vulnerable areas. So leg muscles chest arms and so on. Started shaking uncontrollably. Had to be under shower for ages to feel better. Felt dizziness etc. Had to focus to control breathing and get warm water on my neck first. Working long hours and exercising twice a day, no drinking or drugs. Do I have to worry about exertion tomorrow?
