Vertical ridges protruding on the thumbnail

Vertical ridges or raised lines on the thumbnail may be caused by physiological factors, or by pathological conditions such as nail dystrophy or eczema. Treatment can be achieved through general management or medication. Specific details are as follows:

I. Physiological Factors

If a person frequently stays up late or experiences excessive mental stress, this phenomenon may occur. It is important to get adequate rest and avoid overexertion.

II. Pathological Factors

1. Nail Dystrophy

Long-term picky eating, inadequate nutrition, or nutritional imbalances can lead to nail dystrophy, resulting in vertical ridges on the nails and pain. Treatment may include taking medications such as zinc gluconate granules or calcium carbonate with vitamin D3 tablets, as directed by a physician.

2. Eczema

This condition may affect the nails, causing changes in their shape and structure, leading to vertical ridges and raised areas. Medications such as compound triamcinolone acetonide acetic acid solution or tacrolimus ointment may be used under medical guidance.

In addition to the above causes, vertical ridges and elevations may also result from conditions such as onychomycosis (fungal nail infection), nail psoriasis, or nail lichen planus. Avoid scratching with hands and maintain local cleanliness.
