I'm sorry to hear about the pain and swelling you're experiencing in your knee, interphalangeal joints, and right wrist. These symptoms can be distressing and may indicate inflammation or an underlying joint condition.

Pain and swelling in multiple joints could be related to conditions such as arthritis, including rheumatoid arthritis or gout, among others. One medication sometimes used to relieve such symptoms is a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing inflammation and pain.

For example, a medication like Indocap Capsule is used to relieve symptoms caused by osteoarthritis, rheumatoid arthritis, gouty arthritis, and other musculoskeletal pains. It works by blocking enzymes that produce chemicals causing pain and swelling. However, this medication requires a prescription and should be taken under medical supervision due to potential side effects such as stomach ulcers, increased risk of heart attack or stroke, dizziness, and others.

Recommendations:

• Please consult a rheumatologist or an orthopedic specialist promptly for a thorough evaluation, diagnosis, and appropriate treatment plan tailored to your condition.
• Avoid self-medicating, especially with prescription drugs, without professional guidance.
• If you experience severe pain, sudden swelling, redness, fever, or difficulty moving the joints, seek emergency medical care immediately.
