They're classic remedies, and a lot of people swear by them. Put a cold compress or ice pack (wrapped in a towel) on your painful and swollen joint. Use the ice packs for 15 minutes at a time with 30-minute breaks in between.
Moist heat can help relax muscles and ease aches, pain, and stiffness. Wrap a warm towel or pad around the area that hurts. Or try a warm bath or shower.
