A friend who had surgery to mend a congenital heart defect over five years ago claims it still bugs her to feel “jutting edges of steel that was supposedly used to tie her sternum back together”, presumably when she moves or positions herself wrong. Is this possible, and if so how? I always thought a nerve or brain region being stimulated by something constant like the presence of surgical implants would fatigue quickly and block out the stimulus. Even if the stuff does shift around inside her and vary the sensation somewhat, wouldn’t that feeling merge into the background of all other sensations caused by movement and go unnoticed after five years of exposure?
My friend says she has no idea how what she describes is possible…so I turn to you…
