I have psoriasis since last 6 years. I used medicines first and stopped after that. Last winter it flared up all over body and on scalp also. Then I developed pains in neck, shoulder, ankles. The pain is severe in the morning when I get up. I visited orthopedician and he suggested MRI for cervical spine and shoulder but both are not showing any abnormality except mild AC joint hypertrophy. Did I developed condition of Psoriatic arthritis? Whom should I consult dermatologist or rheumotologist?
