Compression can be applied in a variety of ways to treat lower back pain. The most common forms of compression include ice or heat therapy, wearing a supportive brace or belt, and performing certain stretching exercises. Ice therapy involves applying an ice pack or cold compress to the affected area for 15-20 minutes at a time. Heat therapy involves using a heating pad or hot water bottle to the affected area for 15-20 minutes at a time. Wearing a supportive brace or belt can help provide compression and stability to the lower back. Finally, certain stretching exercises can help to improve flexibility and reduce pain by applying gentle compression to the lower back.
