If I walk any distance or sit for any length of time my hips hurt quite badly making it difficult to continue walking. Should I see an orthopedist or a rheumatologist?
Given a psoriatic arthritis (PsA) diagnosis, seeing a rheumatologist would be the most beneficial first step. Rheumatologists specialize in inflammatory and autoimmune conditions like PsA, and are best equipped to determine whether your sacrum and hip pain is directly related to PsA.

One of the top conditions that can affect people with various forms of arthritis and other connective tissue type disorders as well is called Iliopsoas Tendonitis. This is something I personally deal with as well. It does exactly what you're describing. For this I would see an orthopaedic specialist.
In addition, this can also contribute to secondary Pelvic Floor Dysfunction as well or even be caused by pelvic floor dysfunction as well for which there is a specialized form of physical therapy called pelvic floor physical therapy.
These conditions can face men, women, intersex, and transgender individuals as well (including pelvic floor dysfunction, for which a patient would want a pelvic floor physical therapist. For men experiencing issues, a pelvic floor physical therapist specifically familiar with treating male pelvic floor dysfunction is important).
