Older peoples' attitudes towards
taking pain medication: Are you Martha or Henry?
Martha and Henry grew up in the 1930's and 1940's so they're in their sleep. Pain from their OA has affected their social life and makes it difficult 70's now. People like Martha and Henry have been the subject of many for them to exercise.

Perhaps the most important conclusion to be observed by have OA, some of those habits may not always serve them so wel .
Martha and Henry is that failure to fol ow treatment recommendations Recent research at the Canadian Osteoarthritis Research Program shows for pain medication means that they are achieving less than satisfactory that Martha and Henry may suffer needlessly from OA pain because they pain relief. This results in significant loss in quality of life to themselves, either do not take pain medication regularly, take less than the amount their families and costs to the Canadian health care system. In order to prescribed, or sometimes don't take it at al ! People like Martha and provide an appropriate level of pain relief, people living with OA, like Henry often belittle their pain saying it comes with age, or they state Martha and Henry, and the clinicians that treat them, need to address the they have a high pain tolerance. Often, they make fun of their pain. They reasons why pain medications are not taken in the ways recommended personify it and fight it. They avoid social outings and exercise because to provide the most benefit. of it and fear they may become addicted to pain medication. They say they are not as badly off as they could be while they don't think their friends should have to suffer any pain. They feel that their pain is not life-threatening so it becomes part of their life. They feel proud if they have not given in to it. They say there is nothing they can do about it even though they have not experienced the possible pain relief that might be forthcoming by taking their pain medication (prescription or over-the-counter) as prescribed.
Because of the pain, Martha and Henry can't tie their shoelaces, can't comb their hair, can't walk more than a few steps and can't get enough The role of fatigue and sleep

This leads to confusion and frustration reported by people living with cancer. among people with OA, and their health care practitioners, around • Some people with OA experience considerable daytime sleepiness how best to deal with these complaints.
