It sounds like you might be describing symptoms of subungual melanoma. Here are some key points from my knowledge base:

- Signs and Symptoms of Subungual Melanoma:
- A brown or black vertical line, typically on a thumbnail or big toe nail.
- The line usually starts at the bottom of the nail and can widen over time.
- Nails may lift or separate from the nail bed.
- Sometimes, the nail doesn’t show any discoloration but may be painful, thin, deformed, or cracked.

- When to See a Doctor:
- If you notice changes to the nail that get worse or don’t go away, it’s important to talk to your doctor or dermatologist for an accurate diagnosis and treatment.
