The Glasgow Coma Scale sums three components, each scored at the patient's best response. Mapping each finding:
Eyes open only when hurt $\Rightarrow E = 2$.
Only grunts/groans, no real words $\Rightarrow V = 2$.
Reaches toward the painful stimulus $\Rightarrow M = 5$.
Summing:
\[ \text{GCS} = E + V + M = 2 + 2 + 5 = 9 \]
A GCS of 9 corresponds to moderate head injury.
\[\boxed{\text{GCS} = 9}\]
