Abstract:-Fibromyalgia (FM), myofascial pain syndrome (MPS), and chronic fatigue syndrome (CFS/ME) are chronic muscle pain conditions characterized by persistent discomfort, functional limitations, and impaired quality of life. These conditions share overlapping symptoms such as muscle pain, fatigue, and cognitive difficulties, yet differ in clinical presentation and underlying mechanisms. FM is defined by widespread musculoskeletal pain, fatigue, sleep disturbance, and cognitive dysfunction, often linked to central sensitization. MPS presents as localized regional pain with myofascial trigger points, while CFS/ME is primarily associated with profound fatigue, post-exertional malaise, and unrefreshing sleep. Treatment commonly includes medications such as painkillers (e.g., paracetamol, ibuprofen), muscle relaxants (e.g., cyclobenzaprine), antidepressants (e.g., duloxetine, amitriptyline, pregabalin), physiotherapy, home-based exercise routines, and lifestyle modifications. Symptom management in CFS/ME may also involve pacing strategies, nutritional support, and sleep aids, although no specific curative treatment exists. Adherence to these regimens remains a challenge, particularly Pakistan, despite the high burden of these conditions, there is limited qualitative exploration of how patients manage long-term treatment within the constraints of family practice settings. Objectives: This qualitative study aimed to (1) explore how patients with fibromyalgia, myofascial pain syndrome, and chronic fatigue syndrome perceive and adhere to chronic disease management plans in family practice settings, (2) examine and compare the personal, social, and systemic factors influencing adherence among patients with these three chronic muscle pain conditions, (3) identify which of these conditions appears more commonly among patients seeking chronic pain management in family practice, based on participant representation. Methods: A qualitative exploratory design was employed using in-depth semi-structured interviews with 20 adult patients diagnosed with FM, MPS, or CFS/ME. Participants were selected through purposive sampling based on verified diagnosis, socioeconomic status, and current management in family practice care. Thematic Analysis, following Braun and Clarke’s six-step approach, was used to interpret the data. Results: Seven major themes emerged: (1) Delayed Recognition and Diagnosis, (2) Daily Functioning and Social Impact, (3) Barriers to Treatment Adherence, (4) Healthcare Experiences, (5) Societal Perceptions and Stigma, (6) Shared Illness Experiences, and (7) Recommended Solutions and Future Needs. FM was the most prevalent condition among participants, followed by CFS/ME and MPS. Common challenges included prolonged diagnostic delays, economic constraints, fatigue, limited access to physiotherapy, and stigma associated with invisible illnesses. Positive healthcare interactions were reported; however, systemic gaps and societal minimization of symptoms undermined adherence. Home remedies, spiritual coping, and family support were frequently used when formal care was inaccessible. Conclusion: The study highlights significant diagnostic, socioeconomic, and cultural factors that influence adherence to chronic muscle pain management plans in Pakistan. Improving early diagnosis, integrating mental health services, offering affordable treatment options, and increasing public awareness are essential to enhance adherence and patient outcomes. The findings contribute to closing the gap in understanding chronic muscle pain experiences in resource constrained, family practice settings and provide evidence to guide policy, clinical practice, and future research.
