Step 4: Read and complete the decision guide to learn more about your symptoms.

Positive Rheumatoid Factor

Okay. There are a number of possible explanations for your symptoms and a positive RF (see link below for more detailed information on these conditions).

The positive RF along with the symptoms you mention could be indications of a rheumatologic condition such as rheumatoid arthritis (RA) or a closely related condition.

For example:

  • dry eyes and/or dry mouth with a positive RF may be evidence of Sjogren's syndrome (some people with rheumatoid arthritis have similar symptoms, so the distinction may be difficult)

  • joint pain, rashes and/or mouth sores, and almost any of the other symptoms mentioned are typical in people with lupus

  • tight, shiny skin and Raynaud's may indicate scleroderma.

  • Because you have had rather prolonged joint symptoms along with other problems that could indicate rheumatoid arthritis, lupus or another rheumatic disease, it is important that you contact your doctor for prompt evaluation. These conditions can be serious and early diagnosis and treatment can make a big difference.
