has anyone ever heard of a bone screw coming loose? i f'd up my hand real bad last memorial day and just recently almost over night actually, a hard, circular bump has showed up on my 4th meta carpal right about where i know a screw is. i can actually feel 'something' when i push on it that just doesnt fee like any other part of my hand. i tried a web md search but not sure if i was even doing it righ. i have an appt on tues with the ortho but was just wondering if any of y'all have ever heard/seen anything like that
