Sharp back pains

FTM, Not pregnant 16 months post partum via ECS Currently breastfeeding Any of you have experienced extreme sharp pain on upper to mid left back? Lalo pag nag inhale mas sumasakit, making it harder to breathe. What do we call this po kaya? I've experienced this before, which lasted for less than a minute. Unlike now, I've been experiencing it for more than an hour.
