Joints can absolutely burn with PsA, . I'm sharing a link to some information on symptoms, https://psoriatic-arthritis.com/psa-symptoms, with a link to a specific article about joints, https://psoriatic-arthritis.com/psa-symptoms/joint-pain-swollen-stiff. While the joints aren't necessarily infected, they can be red and painful. Are you currently experiencing new symptoms such a joint pain and burning sensation? Do you have a diagnosis of PsA or other condition? -- Warmly, Christine (Team Member)
