I am currently suffering like you Elvis, and have been prescribed Diazepam tablets as well as painkillers. If you read the instruction leaflet which comes with ~Diazepam you will see that apart from being a general tranquilliser, they are specifically prescribed for reducing muscle spasms which can be one of the main causes of back immobility since they tighten up around your ligaments so much that you literally can hardly move or twist your spine. Following back surgery some years ago I find self-help is the best way of tackling bouts of severe back pain and a helpful exercise is to lie flat on the floor, face down for 5 minutes, letting your back muscles relax as much as you can. Then slowly use your arms to lift your head, shoulders and upper back as far as you can. Hold this arched position for 3 or 4 minutes and repeat three or four times every hour. If you have a disc which has bulged (which is often the cause of back pain) this will slowly help ease it back into alignment but it's a slow process which can't be hurried as it can take a couple of weeks for the resultant inflammation to heal.. If you can persuade somebody to deeply massage the tense back muscles which are in tight spasm this will also help. Beware of driving/operating machinery when taking Diazepam as it can make you very drowy. Ibroprofen is an anti-inflammatory painkiller which is also effective and can be taken in conjunction with the Diazepam, but don't exceed the recommended dose, and don't take the Diazepam for more than about 10 days without re-checking with your GP. Try and consciously check your neck and shoulders for tenseness and regularly exercise them too because tension in this area can transmit itself to other muscles lower down your back.
