Can the blood pressure be different in different limbs?

Generally the blood pressure is slightly higher in the right upper limb than in the left upper limb and higher in the lower limbs than in the upper limbs. But the difference is small, of the order of less than 10 mm Hg. If the difference is higher, it could mean an obstruction in the blood vessel of that particular limb.

Can the Blood Pressure be Different in Different Limbs
Coarctation of aorta

For example, lower limb blood pressure is much lower than that in the upper limbs in a condition known as coarctation of aorta, in which there is a narrowing of the aorta, beyond the origin of the blood vessels to the upper limb, but before the origin of blood vessels to the lower limb. In this condition, the blood pressure in the upper limb blood vessels also rise due to the obstruction. Aorta is the main blood vessel taking blood to the whole body.
