Icing your back is a great way to relieve back pain and offers many benefits for your spine. Here are some of them:

• Relieves pain: Ice helps to relieve back pain because it numbs the area and temporarily decreases nerve activity. 
• Reduces inflammation: Ice helps to constrict blood vessels which helps to reduce inflammation. 
• Speeds up the recovery process: Cold therapy helps to speed up the recovery process because it minimizes tissue damage which optimizes the healing process.
