01
TAP IMMEDIATELY - calf damage feels like cramping, not sharp joint pain.
02
Muscle damage accumulates rapidly with deceptive mild discomfort early on.
03
Do not attempt to tough out compression - muscle tears occur within seconds.
04
Apply pressure extremely gradually; bone-on-muscle contact escalates damage fast.
05
Recovery from calf tears takes weeks with deep bruising and difficulty walking.
