When we observe alterations in the color and quality of the onyx, it can be due to various causes which should not be neglected in any case, these can be fungal infection, injury, onychocryptosis,
pachyonychia, onychogryphia, diseases that affect the quality of the onyx such as diabetes.
All the above causes are quite serious and capable of destroying the onychial plate and the appearance of the nail where it will be difficult to return to its normal state, so it is necessary when we notice discolorations and general alterations in our nails that we have not seen before, to immediately contact a qualified podiatrist.
