Raynaud and Seiver Disease affect the feet, but in different ways. Raynaud’s Disease causes spasms that make the feet cold, while Seiver’s Disease can mimic Achilles tendonitis and can be very painful.
Raynaud’s Disease is a disorder that affects the feet. It is caused by contraction of the smooth muscles controlling the small arteries supplying circulation into the hands and feet. This contraction, or “vasospasm,” makes the arteries so small that they restrict blood flow. Exposure to cold temperature can often bring on a vasospasm.
Raynaud’s Disease is most common in young women, and has no known cause. It typically is found in both feet and both hands.
Pain in the heel of a child’s foot, typically brought on by some form of injury or trauma, is sometimes Seiver’s Disease. The disease often mimics Achilles tendonitis, an inflammation of the tendon attached to the back of the heel.
A tight Achilles tendon may contribute to Seiver’s Disease by pulling excessively on the growth plate of the heel bone. This condition is most common in younger children and is frequently seen in the active soccer, football or baseball player.
Sport shoes with cleats are also known to aggravate the condition.
