Slipped disc?

I’m in agony. Since I’ve come back from Italy I have experience back pain but since last Sunday it got worse. I actually felt my back going and I was stuck while loading the dishwasher. My GP thinks it's a 'slipped disc'. Although this term is commonly used, this type of injury is more accurately described by the terms 'prolapsed disc' or 'herniated disc'. The back pain from this type of injury is caused when the disc bulges or ruptures and the internal material presses on a nerve or the spinal cord, I do not know how the doctor managed to diagnose that without any scans, unless he's got x-ray vision, but I suppose I have to trust him for the moment as the symptoms seem correct. I’ve been prescribed anti-inflammatory tablets, painkillers and referred to the Backpain Clinic at the hospital. But in the meanwhile the pain is excruciating and I can hardly, walk, sit or even sleep. How much I do hate aging!
