What causes toenails get stuck to the flesh, to grow upward (thicken)? See detail?

I don’t know about the other two, but fungus can cause a nail to thicken. I’m not sure what you mean by “upward” in this case, but fungus will also raise the nail higher on the toe.

Wearing shoes that aren’t long enough will also cause toenails to turn in weird directions if they’re worn too long and the nails aren’t cut regularly.

@mrentropy I see too may people who have this. I understand about the tight shoes. Where does the fungus come from by the way? People who do the same care to their toes toenails, one has this condition the other doesn’t.

@flo Beats me. Having your feet warm and moist is probably a factor. Athlete’s foot that has gone untreated for too long, maybe? I really don’t know.

This sounds like a common foot fungus. Not sure what its called but you can get it from unsanitary pedicures, yoga mats, etc.. The doctor will prescribe either a super strong medicine that’s so harsh on your liver that it has to be checked first, or a medication that you have to take once a day for eternity! I say, rub a small amount of vics vapor rub on the nail once or twice a day and it should be gone in a few weeks..

@Stilettos I was reading some websites that said Vic’s can take the nail off, permanently. But it was always the same article on different web sites and never saw anything else addressing that.

Hmm. Well. Thats pretty gross. And would be a real bummer. But I used this method and still have most my toenails. Also my step sister suggested it because she had done it. And my mother. When I asked my doctor about it, he just kinda shrugged it off. But I had taken the medicine that he prescribed that was harsh on my liver, and got reeeeaaallyy sick.. So. I guess you take your chances either way..

Ingrown toenails and ones that curve upwards are typically caused by wearing shoes that do not fit properly. Toenail fungus is a whole other matter and is more likely to cause thickening of the toenail.

@mrentropy by the way by grow upward I meant thicken.
@Stilettos what is that strong medicine that is harsh on the liver?

Patients in nursing homes often have thick, yellow toenails. I don’t know what causes that; they wear slippers, usually.
