Collapse of the middle nail of the right hand may be related to nail trauma, or it may be caused by nail malnutrition, nail fungus disease and other reasons.
1. Nail trauma: If the middle nail of the right hand is accidentally crushed or smashed in the course of daily life or labor, resulting in damage to the nail bed, it may cause the middle nail of the right hand to collapse.
2. Nail malnutrition: It is mostly considered that it may be caused by medicinal stimulation, long-term contact with chemical products, or suffering from psoriasis, lichen planus and other diseases. Due to nail malnutrition, the structure and function of the nail matrix are affected, resulting in nail plate disorder, which may cause the collapse of several finger nails, including the middle nail of the right hand.
3. Nail fungus disease: clinically known as onychomycosis, if the middle nail of the right hand is infected by fungus, due to the invasion of fungus into the nail bed, it may lead to the collapse of the middle nail of the right hand, and may be accompanied by the thickening of the nail bed, and shedding and other manifestations.
If the middle nail of the right hand collapses, it may also be caused by other reasons. It is recommended to consult a doctor as soon as possible to clarify the cause and then give targeted treatment.
