Broken hand at 16, now 23, 2 pins and a cast used, removed pins and cast when "healing" was finished. Bones shift on a daily basis, advice plz?

Perhaps you are . Referring to a joint that is subluxing and slding in and out of place. A commin scenario could involve the cmc joints where the metacarpals meet the wrist but it is very hard to honein on a problem with nonspecific inforamtion. Perhaps an evaluation by a hand surgeon for a problem such as this is indicated as surgery and injury is part of the past history.
