Bursitis normally lasts one to two weeks if treated. Bursitis can affect any joint. If you have bursitis you can do a few simple things at home to help it go away.
More Info: There are three things that help heal bursitis: rest, ice, and medication for pain and swelling. Simply rest the affected joint from repetitive motion. Ice packs can be applied on and off to help with both the pain and swelling. Bags of frozen pea make great ice bags that easily wrap around the affected area. Over the counter pain relievers like Advil or Ibuprofen help reduce the swelling and eliminate the pain at the same time. Sometimes it helps to support the joint by wrapping it in an elastic bandage - just don't get it too tight!
Sometimes bursitis is caused by a joint repeating the same motion over and over again. Other times it is caused by putting too much pressure on a joint. A good example of this would be bursitis in the knee of someone who works on their knees a lot. Bursitis can also be caused by arthritis or by the joints aging. Infection and injury are the other known causes of bursitis.
Many people develop bursitis, but you don't have to suffer endlessly with it. Do a few simple things and you will soon be pain free.
