For arthritis in fingers, several treatment approaches are available. Resting the affected fingers can help reduce pain and inflammation. Applying heat or cold packs can provide relief. Over-the-counter pain relievers and anti-inflammatory medications may be used. Splints or braces can support the joints and limit movement. Physical therapy exercises can improve flexibility and strength. In some cases, corticosteroid injections may be administered. Maintaining a healthy diet and weight is also important. If symptoms are severe, surgical options may be considered after consulting a doctor.
