When you hold the ice cube for a very long time, the enzymes deactivate. Blood circulation stops. The brain initiates impulses for blood circulation. The local nerves therefore get irritated and produce a sensation of heat.
These can lead to tingling and numbness because the tense muscles press on and irritate the nerves. The result is restless legs with pins and needles and sharp, deep, shooting/stabbing bone pain, often accompanied with a burning sensation. This can be excruciating. Another theory as to what causes the numbness and tingling is something called cold-induced vasospasm. About 40% of people with fibromyalgia have cold-induced vasospasm. Blood vessels normally constrict a certain amount when itâs cold, to direct the blood away from the skin and keep the inner organs warm.
