==Evaluation==
*Screen for organic causes of symptoms
*Psychiatric consultation

==Management==

===Reassurance===
*May be successful in young patients with no underlying medical or psychiatric illnesses with clear psycho-social stress
*Unlikely to be successful in patients with chronic somatization
**Perceived as denial of sick role
**Desire for acknowledgment and recognition &rarr; disappointment when no pathology discovered
**Resistance to recovery because "specter of cure" threatens sick role
***Development of new side effects, allergic reactions, and symptoms

===Legitimization of Symptoms===
*Listen and attempt to understand patient's experience
*Explain that patient's illness causes many symptoms but does not lead to medical deterioration
*Offer only guarded projections about patient's condition &rarr; safeguards sick role &rarr; may limit illness behavior

===Diagnosis===
*Clarify precise meaning of terms to avoid misinterpretation
*Somatic responses and descriptions may be better accepted than purely psychiatric diagnoses
**Hyperventilation, tension headache, muscle tension, muscle strain, muscle spasm, and stress
*Communicating diagnostic uncertainty may be helpful
**"atypical pain", "multiple complaints following injury"

===Medications===
*Patient with somatic symptom disorder have a high affinity for medications and are reluctant to discontinue drugs, regardless of benefit
**Prioritize lifestyle modification
**Benign remedies may be helpful &mdash; lotions, supplements, elastic bandages, and heating pads
*Avoid drugs that cannot be safely continued indefinitely
*Avoid drugs that produce abstinence syndromes or dependence
*Avoid pain medications; if necessary, prescribe to be take on schedule, not "as needed"
*Antidepressants may be beneficial, including tricyclics

===Mental Health Consultation===
*Patients resist psychiatric evaluation &mdash; threatens sick role
*Patients fear abandonment &rarr; reassure primary physician will continue caring for them
*Patients may accept treatment as "stress management" or "education" that targets physical symptoms and somatic distress.

===Physician Attitudes===
*Focus on understanding patient's subjective experience
**Avoid telling patient nothing is wrong or symptoms require no treatment
*Avoid counter-transference when no physiologic explanation can be found
**Attempt to retain compassion
**Don't label as "difficult patient"

===Treatment Goals===
*Patients lack insight.  Do not attempt insight-oriented psychotherapy.
*Do not promise or attempt cure &mdash; threatens sick role
**Patient may escalate illness behaviors &mdash; new side effects, allergic reactions, and symptoms
**Reassure that patient will "probably always be ill" and should "learn to live with some pain"
*Avoid unnecessary tests and procedures &mdash; may encourage somatization
*Focus on modification of illness behavior and improved functional status
**Decreased frequency and urgency of medical use
**Avoidance of expensive and hazardous procedures
**Improved work or school performance
**More social activities
**Better personal relationships

==Disposition==
*Provide appropriate psychiatric referrals.
*Discharge with education and instructions.
**There are no alarming findings
**No further testing or medications are indicated
**Ongoing care and reassessment will be arranged
*Follow up with primary-care physician &mdash; becomes gatekeeper for all medical consultation and care.
**Avoid outpatient tests or hospitalization unless indicated by clear objective signs
**Scheduled follow-up on time-contingent basis (every 2-4 weeks)
***Reduce association between medical contact and necessity for escalation of illness behaviors
***Reduce fear of abandonment
