Hello I think we might have something similar here in the U.S. called a functional medicine doctor or like Lori mentioned, an osteopath. Some of the names and types seem to overlap in some places and be different in others- just further adding to the confusion.
I'm saving up to see a local functional medicine doctor, but haven't made the appointment yet since it isn't covered by my insurance and from what I've learned from others, they often advise certain supplements that can also be very pricey.
I have found that following the Autoimmune Protocol (diet) to be very helpful. It might be something similar that was recommended to you. I wrote about my experience and research in a two-part set of articles that you might find helpful. https://psoriatic-arthritis.com/living/dietary-changes-part-1
My approach to managing my PsA involves incorporating pretty much everything I can. I've changed my diet, added gentle yoga stretches, and top off all my vitamins, especially vitamin D and vitamin B (shots). It requires a ridiculous amount of tracking and I don't do nearly perfectly enough, but I try my best.
Hopefully other community member will chime in with their experiences and I'd love to know more of your thoughts about your experiences. -Leanne (Team Member)
