Your toenail turns yellow, cracks, crumbles... Bad news, you definitely have toenail fungus! Onychomycosis (its scientific name) is a very common fungal infection, which is not dangerous, but particularly contagious and unsightly. Fungus of the feet must be treated quickly in order to interrupt the chain of transmission and not to have to lose your nail.
You are not sure if you have nail fungus ? To recognize it, look at your nail. If it becomes red and swollen, sometimes oozing, it's a bad sign. In the same way, you will be able to recognize your mycosis by the thickening of the nail, if it cracks and crumbles. Finally, if it becomes whitish, it is because the mycosis is spreading under the nail. If you do not take any treatment, your damaged nail will not fall off, however it will peel off the skin.
