Final answer:
The recommended treatment for controlling fever and pain in rheumatic fever is NSAID and Aspirin, with caution required for long-term use due to potential side effects.
Step-by-step explanation:
The recommended treatment for controlling fever and pain caused by arthritis and carditis in rheumatic fever is NSAID and Aspirin.
Nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in reducing pain, decreasing fever, and in higher doses, decreasing inflammation.
Aspirin, a type of NSAID, has been used for its health effects for centuries and also inhibits blood clot formation.
It's essential to note that while NSAIDs are effective, their long-term usage can lead to side effects such as gastrointestinal issues, heart attack, and kidney disease.
Therefore, they should be used with caution, and under the guidance of a healthcare provider.
