I am so glad that you got help to lift William, Lady A - but so sorry that you had the added worry, stress and disturbed night.
I'm off to physio today - start of the 3rd round of physio, in the last 3 years, to try and address/help the damage caused by 22 years as a care worker, which stretch back into the 'bad old days', when it was considered 'fine' for me and others to lift our 'clients'. I can't walk more than a couple of hundred yards without limping, stairs/slopes are something I avoid like the plague, and not just my spine, but other joints are now badly affected and the pain is pretty much constant, though thankfully, not always severe. Had a heavy day yesterday, when I was seldom off my feet - and as a result, despite 'maxi strength' prescription painkillers, I've managed maybe 4 hours sleep, spending most of the night in too much discomfort to sleep.
You think that 'lifting someone' as a one off won't hurt, and you think that especially with someone who is slight or small, that it will be 'fine' - but it isn't. The physio thinks a lot of the damaged was probably caused by less obvious actions, too - using hoists on carpeted floor when I did home care, bending and twisting to try and bath or dress a less than co-operative client, catching stumbles and saving falls, allowing clients to 'drag' on my arms when walking. And the 'manual handling courses' are all well and good, but in my experience, a lot of the techniques depend on a certain level of compliance from the person you are caring for, and no challenging behaviour - otherwise they are useless.
Please, please, please, carers - try (and I know its not easy) to take care of your backs xxx
