Care During COVID-19

At Cooley Dickinson Medical Group Rheumatology, we’re committed to taking care of you during the current health care crisis and to upholding our safe care commitment. Telephone, virtual visits and in-person visits are available.


Diagnosis is a crucial element of every medical specialty, but perhaps especially in the discipline of rheumatology. Symptoms that include pain and swelling can be present in the course of numerous conditions including gout, osteoporosis and various forms of arthritis, but the best treatments for each can vary widely depending on the underlying cause of the illness. Increasingly, rheumatology has become a study of the immune system, as more and more of the conditions it strives to treat are linked to autoimmune diseases like lupus, fibromyalgia and psoriasis, which can all cause painful inflammation in joints and connective tissues.

Cooley Dickinson Medical Group Rheumatology treats patients with many rheumatologic diagnoses, including the following conditions:

  • Arthritis
  • Osteoporosis
  • Fibromyalgia
  • Gout
  • Autoimmune diseases such as lupus, scleroderma, and vasculitis

In-office procedures that we perform include:

  • Joint Drainage
  • Steroid Injection
  • Trigger Point Injection
  • Viscosupplementation with Hyaluronate

Integrated care can also be an invaluable tool in helping to treat rheumatologic conditions, and referral to orthopedists, physical and occupational therapists and non-traditional health care providers can be important supplemental prescriptions. Recognizing symptoms and identifying the best, most effective strategies for providing relief are high priorities for this practice; be they pharmaceutical or therapeutic. Conditions characterized by chronic pain are by definition cumulatively debilitative, and can wear down even the most durable among us. Throughout your diagnosis and treatment, the caring professionals of Cooley Dickinson Medical Group Rheumatology advance your health by employing one of the most powerful tools in addressing these conditions—empathy.
