Explanation:

The diagnosis of Psoriatic Arthritis (PsA) is based on the patient's chronic asymmetric joint pain in distal inter - phalangeal joints (DIPs) and the presence of erythematous skin plaques. Imaging like X - rays of hands and feet can help detect joint space narrowing and pencil - in - cup deformities, with possible follow - up MRI or ultrasound. Labs such as RF, ESR/CRP can aid in assessment. Referrals to rheumatology and dermatology are recommended. In chiropractic treatment, aggressive joint manipulation in affected joints should be avoided and co - management with other specialists is advised.

Answer:

1. Diagnosis: Psoriatic Arthritis (PsA) due to chronic asymmetric joint pain in DIPs and skin plaques.
2. Recommendations/Referrals: X - rays of bilateral hands and feet for joint assessment, possible MRI/ultrasound, labs (RF, ESR/CRP), referral to rheumatology and dermatology.
3. Chiropractic treatment: Avoid aggressive joint manipulation in affected joints, co - manage with rheumatology and dermatology.
