Rotation means a system, not randomness
Rotating sites doesn’t mean picking a different spot at random each week; it means following a repeatable pattern so that no single small area gets used too often in a short stretch of time.
A simple pattern that works
Divide each major site (abdomen, left thigh, right thigh, left arm, right arm) into a few zones. Work through them in a fixed order, then start again from the beginning once you’ve cycled through. A basic log entry each week, noting which zone was used, is what makes this actually trackable rather than a vague intention.
Spacing within a single site
Even within one site, like the abdomen, spacing consecutive injections a few centimetres apart avoids repeatedly hitting the exact same small spot, which is a subtler form of rotation that a zone-based system alone doesn’t fully cover.
Why consistency matters more than complexity
An elaborate rotation scheme that’s hard to remember gets abandoned. A simple, written-down pattern that’s actually followed every week is far more effective at preventing site overuse than a complicated system that only gets followed sometimes.
Adjusting for what you notice
If a particular site consistently shows more irritation or discomfort, it’s reasonable to reduce how often it’s used, even if that means adjusting the rotation pattern slightly. A log makes this kind of pattern easy to spot.
