For ones veins or muscles to become strained by carrying
something too heavy.
Nagtakano ta tang sakong belat, nagsit da tang
boko-bokō, sigoro nagkibit tang ogato.
I carried a heavy sack of rice, my back is hurt, maybe my veins
have been strained.
People say that the problem with a muscle strain is really with the
veins, which have become twisted up. To relieve the problem, the
area should be massaged.
