9. Compression
Compression is the technical term used for wrapping a bandage around an affected area, using a compression sock, or using a compression tube. All these methods achieve effectively the same things: helping to prevent additional fluid from building up in the area and even help to reduce the swelling by driving out what is already there.
Compression also has an additional benefit: that being to help support the joint and the muscle through the range of motion when engaging in exercise or normal activity. Should you have injured your elbow for instance, then wearing a compression sleeve can help you to more safely practice such things as bicep curls or even light sports with a lower chance of injury. Similar, you may also use a splint to keep the area still during activity.
This can be a useful way to manage a graded return to your usual activity as the symptoms begin to improve.
