Thanks for your message. I wish you fast recovery. Unfortunately, internal vibrations haven't been studied much yet. One of my doctors reply to me was if doctors thought internal vibrations were important, this subject would have been studied. He has no clue.
As for me, at rest, they are usually felt more. I still have them, mostly felt at nights. I think they are still 24x7 but I feel them more intensely at rest. I also have pain on the left side and weak muscles in comparison to the right side. I wish I knew what to do...
