Hi , yes, that is definitely an advertisement. Personally, I am a bit skeptical when companies that are trying to sell me things say they can fix any issues that even the doctors are still trying to figure out. That being said, I can appreciate your need to know what might have triggered your PsA. Unfortunately, autoimmune conditions can be so tricky, and I know that doctors and researchers too would like to be able to definitively say why or what causes these conditions. Have you ever been diagnosed with psoriasis? I ask this because a large majority of people with PsA have psoriasis as well. Genetics can also (but not always) play a roll in autoimmune disease as well. I think I shared this article with you responding to another of your posts, but I'm sharing it here as well, just in case, https://psoriatic-arthritis.com/psa-basics/cause-triggers. It has some information on triggers of PsA. I do hope that you can get some answers and helpful information! Are you working with a rheumatologist? Wishing you a gentle day. -- Warmly, Christine (Team Member)
