What should I do about swelling and pain on the sole of the foot caused by rheumatoid arthritis?
Disease description:
My grandfather has rheumatoid arthritis, and his foot sole has been slightly swollen and painful these days. I would like to ask, what should be done for swelling and pain in the foot sole caused by rheumatoid arthritis?

Rheumatoid-related swelling and pain on the sole of the foot can be relieved through the following measures:
1. **Medication**: Take non-steroidal anti-inflammatory drugs (NSAIDs) or antirheumatic medications to alleviate pain and swelling. If necessary, corticosteroids may be used under a doctor's guidance.
2. **Physical therapy**: Methods such as warm compresses, massage, and acupuncture may help improve blood circulation and reduce swelling and pain.
3. **Daily care**: Keep the feet warm and avoid cold exposure; elevate the feet appropriately to promote blood return and reduce swelling; minimize walking and standing to avoid excessive strain.
4. **Medical consultation**: If symptoms persist, seek medical attention promptly.
The specific treatment plan should be determined based on the patient's condition and the doctor's recommendations.
