Treatments for swollen finger joints depend on the cause, but include taking non-steroidal anti-inflammatory drugs, using steroid medications and applying ice or heat, according to WebMD. Patients who suffer from swollen joints due to arthritis should follow a doctor's treatment plan. Some causes of a swollen joint include gout, injury, osteoarthritis, reactive arthritis, septic arthritis and psoriatic arthritis.
Applying ice packs helps to reduce the pain and swelling of a swollen joint that is caused by an injury, notes MedlinePlus. Nonsteroidal anti-inflammatory drugs work effectively for swollen joints resulting from an injury or arthritis. Oral steroid medications taken for a short period help to ease painful swollen joints. They work by blocking the production of inflammatory chemicals in the body. A steroid injection directly into the joint is another good treatment, but it only offers temporary relief.
For swollen joints caused by inflammatory types of arthritis, such as psoriatic arthritis and reactive arthritis, treatment often includes steroid medications, NSAIDs and other medications that improve the immune system, as reported by WebMD. Joint swelling caused by gout is treated with a medicine known as colchicine, which eases pain and inflammation. Treatment for swollen joints caused by infectious arthritis include antibiotics that help to stop the infection.
