When the Bursa gets inflamed it causes pain and swelling which is called Bursitis. This rheumatic disease only affects the soft tissue around the joints and can be triggered by either overuse or an injury, an incorrect posture or abnormal position of the joints.
It can also occur in combination or due to other diseases and conditions and sometimes might be a result from an infection. Don't be surprised though, when it turns out that there can no actual cause be found for it: this happens more often then not.
A physical exam will show if you would be dealing with Bursitis and there are several treatments to ease the pain and inflammation. Medications like NSAIDs, Corticosteroids and Antibiotics can do the trick. Rest and splints can help speed up the healing, as well as applying heat or cold. In some cases physical or occupational therapy might be helpful and when push comes to shove, surgery would be a last resort.
When given time, many of these conditions can or will go away on their own, but patience is not something we like to practice when we are in pain.
The same goes for problems, actions or words, done to us in life. When given time, God will solve them in His time and in accordance with His will. We have to learn to practice patience, even when we are in pain. :-)
But let patience have its perfect work, that you may be perfect and complete, lacking nothing.
