At Portland Pain Solutions, we offer a wide variety of services. Dr. Frederick C. Littlejohn focuses on consultations and interventional pain treatment, as well as other treatments designed to improve quality of life. One of the benefits of being a small, boutique practice, is that we take the time needed to get things right when we have that luxury. But when time is of the essence, we get the job done far faster you would ever expect. Work that would take weeks or even months to do within a large institutional system takes days here.
