The raised toenail cap with horizontal lines is considered to be related to trauma, or it may be due to nail dystrophy, onychomycosis and other diseases.
1. Trauma, if you often wear inappropriate shoes during walking or run for a long time, it may lead to the toenail cap being compressed, so there will be the symptom of transverse bumps on the toenail cap.
2. Nail dystrophy, some patients with nail dystrophy will lead to changes in nail morphology and structure, nail separation, nail plate thinning symptoms, but also may lead to the toenail cover with horizontal lines.
3. Nail groove inflammation, patients with nail groove inflammation due to the nail groove area by the inflammatory stimulation, may lead to the nail groove red, swollen, pus, but also may appear in the nail groove tissue lesions, resulting in the toenail cover with horizontal lines raised symptoms.
If there are obvious symptoms, you can promptly consult a doctor for examination and treatment.
