Acromyotonia Site

Symptoms are often worsened by cold temperatures or repetitive movement, leading to a "locked" or "solid" feel in the hands.

It is a form of myotonia where the distal muscles, particularly the hands and feet, fail to relax immediately after voluntary contraction.

It should not be confused with the (part of the shoulder) or acromegaly (a growth hormone disorder).

The affected area can feel like a solid, immovable piece, similar to a spasm. It is often a symptom of underlying neuromuscular disorders rather than a disease on its own.
