Hi and thanks for using the forum.
The back pain and vibration feeling could be related. Sometimes, when nerves are affected, symptoms such as a feeling of vibration can appear. If this feeling has persisted, or if you are getting the vibration feeling frequently, then you should get checked out by a neurologist or a spine specialist. He/She can let you know if they think the two are related and may be able to help you alleviate this feeling. Good luck.
