What should you know about thick growth under toenail?

Short answer
Thick growth under a toenail is often nail debris or thickened nail tissue from fungus, psoriasis, injury, or pressure, and it needs assessment when persistent.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

What may be underneath
Material beneath a thick nail may be compacted keratin and debris, while the nail itself may have lifted from its bed. Nail fungus can cause crumbly material and altered colour. Nail psoriasis may cause lifting, pits, or tenderness around the nail. Pressure from footwear and previous trauma can also change the space beneath a nail. A dark area is not automatically an infection; a clinician should assess new pigment, especially when it forms a band or reaches nearby skin.
Care without injury
Wash and dry the foot carefully, use roomy footwear, and trim only the free edge with clean tools. Do not insert sharp objects under the nail, tear it away, or share clippers. If a fungal cause is confirmed, possible discussions include Nail Fungus care, Laser Treatment For Nail Fungus, or Oral Antifungal Treatment. Treatment should match the diagnosis, other medicines, and the health of the nail root.
Signs that need review
Arrange an examination if the material keeps returning, the nail is lifting, or walking becomes uncomfortable. Seek prompt care for pus, spreading redness, warmth, swelling, bleeding, or severe tenderness. A new dark streak, colour that extends onto the surrounding skin, or a nail change without an injury deserves timely review. Do not delay foot assessment if you have diabetes, reduced sensation, circulation problems, or lowered immunity.
What to ask
Ask whether the material should be tested, whether the nail bed or surrounding skin is involved, and how to protect the area while it grows out. Mention trauma, footwear pressure, colour changes, pain, drainage, and other affected nails.

Questions people ask
Can I scrape out growth beneath the nail?
No. Scraping can injure the nail bed and surrounding skin; trim only loose free edge and seek advice if material persists.
Does dark material under a nail always mean fungus?
No. Trauma, pigment, dried blood, and other nail changes can look dark, so a new or spreading mark needs examination.
