I have got a problem with my nail. it looks like nail fungus. Actually I've had it from so long that I cannot remember when or how it happened. I am 17 now. it was definitely there from 10 years. I have never consulted a doctor to check it either. the nail looks kind of green in colour and is cracked in the middle. it maybe be nail fungus but I cannot say for sure.
Please check this picture of the nail:
Any idea what this is, and how it can be cured?
You should have taken it to the doctor. Cures like tea tree oil and oregano oil are best suited for the job. I suggest you go see this site. it has great reviews on toenail fungus cures.
