Your injury must be because of an accident
Sometimes injuries aren't caused by an accident. We don't cover:
- illness, sickness, or contagious diseases, eg measles
- stress, hurt feelings or other emotional issues. This is unless they're linked to an injury we already cover
- conditions related to ageing, eg arthritis
- most hernias
- injuries that happen over time, unless an activity at work is causing it
- damage to items that don't replace body parts. This includes hearing aids, glasses, pacemakers and gastric bands.
楼主请看上面的链接和内容。尤其是黑体加粗的部分。一般来说，长时间积累造成的伤害ACC是不管的。但是这里有一个例外，就是如果你的伤害，是由于工作活动造成的，那么ACC是有可能Cover的。
你的情况，后背疼是因为工作造成的。属于OOS的情况，也许ACC可以Cover也不一定。
但是如果我是你，会先跟公司说一下，看看可不可以换个椅子，提供一个背背佳，或者提供免费或者公司资助的按摩服务。
