Final answer:
The MSI perspective on back pain involves a multidisciplinary approach that includes psychoneuroimmunology, which might be relevant to Marisa's post-treatment symptoms, although her case also requires investigating other potential causes.
Step-by-step explanation:
The MSI perspective on back pain combines multidisciplinary approaches to understand and treat pain. Although not directly related to Marisa's case of abdominal pain and swollen lymph nodes following treatment for a compressed spinal cord, the MSI perspective might consider the role of psychological and immunological factors in her symptoms. The reference to Kiecolt-Glaser et al., 2002, Psychoneuroimmunology and psychosomatic medicine: Back to the future suggests exploring the interaction between the mind, nervous system, and immune response in the context of pain and healing. In Marisa's case, it may be beneficial to look into psychosomatic factors that may be exacerbating her pain experience after her spinal treatment, although her symptoms also demand a thorough investigation into potential infections or other medical conditions.
