He has been snapping at you during dressing, pacing at night, pushing away food he liked last week, and when you ask what is wrong he says nothing, or says nothing at all. As language fails, pain does not leave, it changes how it speaks, and this page teaches you to hear it, since unrecognized pain is one of the most common findable causes of everything on that list.
Before you answer the snapping with a correction, notice what is rising in you, whether it is the sting of being snarled at or the exhaustion of one more task turned into a fight. That is yours, it is normal, and it is worth one breath before you go looking for what his body is trying to say.
Before you go hunting for hidden pain, run the two-minute comfort sweep, because a full bladder, hunger, thirst, a room too hot or cold, a waistband cutting in, or glasses and hearing aids sitting on the dresser all produce misery that looks like mystery, and every one of them is fixable before lunch.
When the words go, pain does not go with them. It moves into behavior, so it shows up as snapping during the sleeve, pacing at two in the morning, pushed-away plates, resistance to the bath, or a man simply going quiet and far away, and families end up managing the behavior while the pain runs on underneath it. He is not being difficult. He may be hurting, and the disease has taken the sentence he would have used to tell you. Hold this honestly in both hands, though, because behavior is not always pain, and this page is where the search starts, not where it ends.
So learn to watch the way the professionals watch, without needing their scoresheet. The face: grimacing, a tightened brow, a look you will come to recognize. The sounds: moaning, sighing, calling out, a groan on movement. The body: guarding a limb, bracing, rigidity, pulling away from touch, a hand that keeps drifting to one hip. The breathing: fast or labored at rest. And whether comfort comforts, because distress that reassurance cannot touch points somewhere physical. One more thing the checklists miss: pain wears his face, not a standard one, so think back to how he acted with pain before the disease, the stoic silence or the short temper, and expect that man to show up again.
Then use the single most revealing technique this page has: watch him move. Pain hides in a chair and declares itself in motion, so study his face during the chair-to-standing moment, on the stairs, while the sleeve goes on, and note exactly where in the movement the wince lives, because that locates what he cannot name. While you are looking, survey the quiet places pain lives in this disease: the mouth (a cracked tooth or a denture sore can poison every meal), the bowels (constipation is common, painful, and invisible until someone asks), the joints that hurt only on movement, and the feet, because nobody undresses the feet, and socks hide a great deal. And if something new and sudden appears, mention it to the doctor without reaching for the familiar explanation first, since this site's standing advice applies here too: name what you see, and let the doctor find the cause.
Print the one-page log if you want somewhere to keep this, and take it to the appointment.
This is what the tracking is for. A dated log of which movement, where the wince lives, and what settled him turns a vague worry into something a doctor can examine.
He may never find the word for what hurts, and you can still find the place. Your eyes on his face during the sleeve are the exam that happens before the exam. Notice it, write it down, and let the doctor do the rest.
