It may be that your friend’s problems are not appropriate for the Pain Clinic to deal with, as they do have specific referral criteria, and the demand is higher than capacity. They don’t generally provide this very tailored multidisciplinary intervention service for people with age related mobility problems, because those problems are not usually amenable to that approach. . If I were her I would request a further GP appointment to explore other options, perhaps with a referral to the community services outreach team, who could provide support such as a course of physiotherapy, occupational therapy support to assist with daily living tasks, or care services.
