Hello, , thanks for reaching out. I'm sorry to hear that you're dealing with leg weakness, but I'm glad you reached out here. As you can see, you're not alone. Fatigue can hit any part of the body, including the legs. One of our advocates wrote about PsA in her legs and, while her experience leans on the side of increased pain, I thought you still might be interested in the article, https://psoriatic-arthritis.com/living/ankle-swelling-leg-pain. Have you had a chance to talk with your doctor about how challenging even simple tasks have been because of the increase in leg weakness? If not, I really encourage you to do so. They can hopefully determine if the weakness is indeed related to PsA or something else entirely and treat accordingly. In the meantime, hopefully some other community members can also share their experiences with you. Sending you gentle hugs. -- Warmly, Christine (Team Member)
