I have very minor beau's lines because a few weeks ago I had constapatipn bad enough that I vomited what food I put in. So for a week after it started moving, I had to be very careful how much I put in. Horses also get those lines.
so the thumbnail for the video showed white lines in you nail and you didn't say anything about white lines in your nail once in the video? my left big toe has ripples and has since I smashed it really bad years ago at work, guess it's just weird now

Who else checked their nails to find out if somethings wrong.
jumpsteadywill (3 months ago)
Truer words have never been spoken..."Don't get all your medical advice from the internet!", but some is apparently okay...BTW, the internet says in no uncertain terms that everything that you are showing symptoms for is cancer, and certain death...so I would argue that no advice should come from the net...just cat videos and baby pictures...

That dark streak scared me before he mentioned that it's pretty common in people with darker completions. I mean, I'll still mention it to my doctor. But, I'm less nervous

My toenails grow incorrectly, causing constant ingrown toenail on the big toes. After several fixes at the GP, I was sent to have my toes cut open, nail bed removed on one side, and treated with (iirc) Hydrochloric acid, now they grow normally. Just thought that might be interesting.
Ks 412 (3 months ago)
What if i have a vertical ridges on my left big toenail but all the other nails are find & my right foot also? But its just one ? & its kinda yellow at the tip i havent painted my nails a dark color since last year maybe sep or oct.

Yo Hank, Nerdfighter here. Is there any chance you'd allow me to translate your videos and upload them to your show? Many people are intimidated by the medical terms and, well, how fast you talk. So could I? Pretty please? Cherry on top and whatnot?

Éowyn Bates (7 months ago)
So what about when a nail falls off and then regrows back? My pinky and big toe nails have never looked the same since they fell off after loosing them to hiking way back in the day. Will they ever look normal again, or is the damage permanent?

This was cool.
MyKayla Hill (8 months ago)
Btw just so people know if you use dark pigmented nail polish and don't use a non-yellowing base coat you can see the tips of your nails change colors. As long as your cuticle growth (new nail growth) doesn't look yellow you should be fine, but start using a proper base coat to prevent yellowing.

My fiancé is dealing with foot trouble for many years and without any luck, he can’t discover the ideal treatment for it. Of all the possible alternatives he tried, only this toenails fungus treatment “amazing womwom site” (Google it) seems to have done the job effectively. Truly would recommend to anyone who inquired.
