When I had really bad backache the other week I rang midwife and she referred me to physio. The backache is mid back and happens if I am at my desk and after a bit means I have to stop working for the day. It is okay in bed and disappears by morning. But as I am still using my desk a lot (have adjusted chairs and monitor height etc) it comes back most days. I've now got a physio appt - would it be wrong to use it when other people may need it more - I mean I know how to to avoid the backache - just don't sit at my desk (though I need to for work).
