Is it possible just to get used to any kind of pain/discomfort? I think it's an issue of degree/necessity, prospect, and choice.

Degree/necessity: How bad is bad? One person may be able to get used to what they judge to be level 5 or 6 pain, while another may have difficulty with what they judge to be level 3 or 4. Some sources say that the goal of pain management is to 1.) reduce the sense of suffering and 2.) improve the quality of life. That's pretty vague, and leaves a lot of room for interpretation. Pain Management doctors evaluate patients according to (among other factors) what effect pain has on their day-to-day lives—are they (patients) able to get enough healthful sleep, are they able to take care of their day-to-day needs (work, school, chores, errands, paying bills, hygeine, etc.), is there excessive preoccupation/obsession with pain, major depression, etc. In short, are they able to function, and how well.

Prospect: Is it harder to get used to discomfort when there is no prospect of relief, or when there is prospect of relief, but one (for whatever reason/s) can/does not avail oneself? This brings us to...

Choice: For whatever reasons, people make choices about whether to seek/accept some kinds of medical help/treatment or to forgo or discontinue them.

Only you can decide how bad these sensations are, and if you can/will be able to just get used to them. Time will help some; life has an indomitable ability to adapt and persevere.
