A chronic condition marked by widespread musculoskeletal pain, fatigue, sleep disruption, and cognitive symptoms — often treated symptomatically rather than at the root.
Pain, exhaustion and poor sleep that no one can explain?
You’re not alone. Many of Dr. Kellman’s patients arrive after years of unexplained symptoms and being told their labs look normal. His job is to keep looking.
Fibromyalgia amplifies pain signals, causing patients to experience pain from stimuli that wouldn't ordinarily cause it. Body pain lasting more than three months, GI symptoms similar to IBS, and reduced exercise tolerance are common markers.
Because the cause is not fully understood in conventional medicine, treatment often focuses on symptom management alone.
Rather than categorizing symptoms under one diagnosis, Dr. Kellman looks for the underlying cause — frequently inflammation and gut-brain signaling disruption — and builds a protocol addressing that root driver.
Treatment may include targeted anti-inflammatory nutrients, gut microbiome repair, and whole-body red light therapy to stimulate deep healing and reduce pain.
Fibromyalgia is a long-term condition that causes widespread pain along with fatigue, sleep problems and difficulty thinking clearly. Researchers believe it involves changes in how the brain and nerves process pain signals, a process called central sensitization. It is more common in women, and it is real, even though routine tests usually come back normal.
There is no single test for fibromyalgia. Diagnosis is based on the pattern and duration of symptoms, after other conditions that can look similar have been considered. These include low thyroid, vitamin D deficiency, anemia, autoimmune conditions such as rheumatoid arthritis and lupus, sleep disorders and Lyme disease. Testing is chosen to rule these out.
Dr. Kellman looks for factors that may be contributing to symptoms, including sleep, thyroid function, nutrient status, inflammation and gut health. Plans are individualized and may combine conventional treatment, nutrition, gentle activity, sleep support, microbiome support and in-office therapies such as whole-body red light therapy and PEMF. Care can run alongside your rheumatologist or other doctors. Patients are seen in Midtown Manhattan and by telehealth.

No. Fibromyalgia isn't classified as an autoimmune disease, but it can occur alongside autoimmune conditions such as lupus or rheumatoid arthritis, which is why they're checked for.
Rheumatologists and primary care doctors usually diagnose fibromyalgia, and pain specialists and integrative doctors are often involved in treatment. Dr. Kellman focuses on contributing factors such as sleep, thyroid, nutrients and gut health.
