Introduction
Suddenly having one fingernail thicken may be caused by factors such as nail dystrophy, nail trauma, or paronychia, and treatment should be based on the specific cause. If a patient has long-term picky eating habits, inadequate nutrition, or nutritional imbalance, it may lead to nail dystrophy, resulting in symptoms such as nail thickening and pain. In such cases, medications like zinc gluconate granules or calcium carbonate with vitamin D3 tablets can be taken under medical guidance.
Sudden thickening of a fingernail may be caused by factors such as nail dystrophy, nail trauma, or paronychia. Treatment should be based on the specific underlying cause. Details are as follows:
1. Nail Dystrophy
If a patient has long-term picky eating habits, inadequate nutrition, or unbalanced diet, it may lead to nail dystrophy, resulting in symptoms such as nail thickening and pain. Under medical guidance, medications such as zinc gluconate granules or calcium carbonate and vitamin D3 tablets (4) may be taken.
2. Nail Trauma
If the nail area suffers external impact, local blood circulation may be affected, leading to swelling and hardening. Under a doctor's guidance, medications such as ibuprofen sustained-release capsules or penicillin V potassium tablets may be used for treatment.
3. Paronychia
This is an infection caused by bacteria. Due to inflammatory stimulation, the nail may become abnormal, leading to thickening or separation of the nail. As directed by a physician, topical treatments such as fusidic acid cream or triamcinolone acetonide and econazole cream may be used.
Besides the causes mentioned above, nail thickening could also result from conditions such as onychomycosis, psoriasis, or lichen planus. It is important to adjust your diet and increase intake of protein-rich foods.
