My back is miserable on land but I am fortunate it rarely bothers me in the water. As ColoDale said keeping your body in one position for any length of time can cause issues.

The lotus position or pulling your knees to your chest. Good on safety stops especially if you have a mooring line. Moving your position a lot can mess with some peoples air consumption so sometimes smaller is better.

Picking out the best exercises that relieve your pain and doing them regularly can help you everywhere.
