Marissa N. Lassere is a rheumatologist in Sydney, NSW, Australia. She looks after people with long-term joint and muscle problems, as well as some inflammatory and nerve-related conditions that can go along with them.
In day-to-day care, this can mean helping patients with arthritis that flares up and settles down over time. Common examples include rheumatoid arthritis (RA), psoriatic arthritis, ankylosing spondylitis, and reactive arthritis. She also cares for people dealing with gout, synovitis, and infections that affect a joint, like septic arthritis and infectious arthritis. At times, inflammation and tissue damage can be part of the picture too, including necrosis.
Symptoms can look different from person to person. Some people come in with painful, swollen joints. Others are dealing with stiffness, trouble moving, or pain that keeps coming back. There are also skin and related issues that often travel with the inflammation, such as psoriasis and shingles.
Her work can extend beyond the joints. Rheumatoid lung disease can be part of RA for some people, and it needs careful attention alongside the joint symptoms. She also manages conditions linked to nerves and pain, including neuralgia, mononeuritis multiplex, and at times sciatic-type pain like sciatica. Some patients are also referred with back or nerve problems, including herniated disk.

Overall, the focus is on practical, ongoing care for inflammatory and painful conditions, with support across the different ways these illnesses can show up in the body.
