You should probably see your doctor and get an MRI scan to see if you damaged a disc in your spine by lifting the bucket.
The vertebra - bones of the spine - are separated from each other by tough little pieces of tissue called discs. They provide padding between the bones. Wrong lifting techniques and old age among other things can weaken and rupture the discs slightly, resulting in very very nasty pain. Once a disc is damaged the pain may reccur for the rest of your life if you lift badly or twist or bend in a way that sets it off. If the rupture gets worse the pain gets worse and you also have some risk of the spinal cord which runs inside the vertebra being irritated or squashed. This can result in numbness in parts of your legs or feet which if not treated can become permanent.
Bad backs are so common many people do just put up with them, particularly if medical insurance is a problem. That doesn't mean to say you should ignore this pain and not try to get a proper diagnosis and advice on your options. You don't want to make it even worse by not understanding what you might be doing wrong.
