I'm looking for a word or short phrase that means something that is not distracting. More specifically, something previously distracting that has since faded into... well, I don't know into what.
So I have this:
"A serious injury to a limb will often cause pain and agitation when using that extremity. A broken leg, for example, will be incredibly painful to walk on.
Minor wounds such as cuts or bruises typically heal quickly, often becoming [no longer distracting] within a few hours."
Any ideas? I looked for antonyms of bother and distract and such, but they were all too positive or not very specific, like "calm" or "soothe" or "not bother". I'm looking more for something that the subject is indifferent to.
The current structure isn't critical, so rewrites are possible, but a single word would be better.
