I thought that my house was vibrating due to the rock quarry doing some blasting as they normally do, so had no worries. But I started worrying when it was 11:23 pm and the quarry shut down at 5pm because I realized that it was my body that was jumping and I could not stop it . What's happening?
A sensation of vibration, especially in the feet, is common in MS. “Body Jumping” is something entirely different. This could be anxiety, shivering, a tremor or something called myoclonus. You will need to talk to your MS doctor about this but it doesn’t sound serious or even urgent based on the information you provided.
