The medical history can
difficult to obtain for many reasons. A patient’s description of his illness
can be affected by his perception of it, his experience with it, and what he imagines about it. By his
expectations. By fear or denial. Or he may simply lack the language to express
it.
“Perception is reality.”

For example, if I had
to tell you what has been going on in my left foot for the past six weeks, I
would be hard pressed to describe it. You would be left scratching your heads.
It all started with localized pain during weight-bearing (but no tenderness to touch).
It started to swell, and then, after four weeks, I noticed bruising. I don’t
recall any injury. It’s hard to know what triggers the pain because it seems
worse at night for some unknown reason. I have no idea why it is getting worse
despite the fact that I have been faithfully resting my foot like I know I
should. It frustrates me because I can’t exercise. It worries me, too. What if
I need surgery? What if I can’t take care of myself?
Even though I’m a
physician, and I know all about strains and sprains, overuse injuries and
stress fractures, tendonitis and arthritis…I can’t really describe the
discomfort. And because I don’t remember injuring my foot, I can’t make sense
of it. This is weird.
Imagine how difficult
it must be for patients to describe their symptoms or to make sense of their
illnesses when they have neither knowledge, experience, nor language for what
is happening to them.
“Write hard and
clear
about what
hurts.”
~Ernest Hemingway~
Most people are not
used to thinking about their symptoms in the kind of descriptive terms physicians
depend upon to narrow the diagnostic possibilities. For example, they might not
realize that the difference between a headache that is generalized, dull and
steady rather than unilateral and throbbing may distinguish a tension headache
from a migraine. They may not be able to distinguish between the kind of pain
caused by heartburn and myocardial ischemia. They might not use those terms to
describe it at all. The patient is more likely to view his symptoms in terms of
lost wages, his inability to provide for his family, or his own impending
decline rather than the onset, character, and duration of his symptoms.
“Every sickness has an alien quality,
a feeling of invasion and loss of control
that is evident in the language
we use about it.”
~Siri
Hustvedt~
Severity is especially
tricky to assess. It depends to some extent on the patient’s innate tolerance
for pain. Is he a stoic or a whiner? His perception of pain depends upon how
his symptoms affect his mood, his ability to carry on, and his fears which are
largely based on what he has heard, what he imagines, or what he has witnessed
in others.
Take it from me, under the best of
circumstances, the medical history can sometimes remain a mystery.
“One day I will find the right words
and they will be simple.”
