Actually, about 1 in 5 people with RA develop carpal tunnel syndrome from the disease, in which the nerves controlling the sensation and movement of the hands are compressed, according to UpToDate. This issue can cause aching, numbness, tingling, and weakness of the fingers and part of the hands.
Sometimes, constitutional symptoms (those that affect the whole body) precede joint symptoms by weeks to months, and may be an early sign of RA.
These symptoms, which may also develop after joint symptoms, include:
- Fatigue or tiredness
- Feeling ill and weak
- Low-grade fever
- Decreased appetite
