Dear people, what do you think - could vibrations by a machine applied to the head cause damage? I tried cryotherapy for double chin (finally have a desire to be pretty) but I felt vibrations in my head for about 45 minutes. I tried not to worry but now I feel very tired and dizzy. What do you think?

I don't feel well know and I don't know what happened and could vibrations cause concussion, subconcussive impact or something that hurts the brain.

I had a concussion one year ago and I'm still recovering and if I have done damage to myself now, I'll be hopeless.
