My husbands wrist is swollen. he does have some pain. he did not hurt it and did not get bit . just wondering what the problem could be.

Arthritis ?: The wrist is an uncommon spot for osteoarthritis, so he may have inflammatory arthritis. Try ice, a wrist splint, and over the counter medications such as Acetaminophen or Ibuprofen if needed. If there isn't any improvement in a few days, he should see a doctor.

Not enough info: Your info isn't specific enough. Where does it hurt? When does it hurt? What is the pain like - burning, stabbing, electricity, ache? What lessens the pain?
