When Health and Music Clash

So I have to do at least 3 sub-cutaneous injections into my abdomen every week.
This requires injecting a medication directly under the skin before you find any muscle. Two of these injections are the same medication and take about 30 minutes of rest to get to room temperature, 10 minutes of mixing the medication into the sterile saline, then a little less than 2 minutes to push in the medication itself.
That may not sound like much, but injecting only 3mL of fluid over 90 seconds or so takes patience and some focus. It also takes little movement.

In music, as a singer, I have been trained and trained and trained to breathe with my abdomen versus my chest. It starts out very uncomfortable at first, but eventually it becomes simply the way you breathe. As a vocalist, allowing your breath to expand in your lungs to the point where your ribs, abdomen, back, and entire torso also expands with it, is one of the earliest and most basic principles.

As it turns out - for the most part, breathing in this way also helps to breathe through pain and testing. It helps in various ways.
The only way I have really noticed it being an issue is when I am doing an abdominal injection that takes some time.
If I am not focusing on breathing higher up in my chest, breathing from my abdomen can sometimes affect the depth of the needle - which isn't good.
So I either have to keep pinching my abdomen so that when I breathe the needle doesn't slide a little out and then inserted further, or I have to breathe high (which feels unnatural to me).

It's not a big deal, but I do find it interesting, all of these routines and practiced traits that wind up being potentially detrimental as far as health is concerned.
