Is two toenails uncommon? Should I be concerned?

I have a similar problem. I am 13 and my toenails have always been short due to me picking them all the time (I've now grown out my fingernails so I can now stop with the picking as it'll ruin them.) One day my second toe had separated from the nail bed - or so I thought. I have now figured out it is a separate layer that has lifted up! I freaked myself out about it until I thought I was going to throw up with stress and worry... But I just want to ask you guys if the bottom layer reattaches to the top one once it has started growing again, this is my last worry about it. Seriously, I thought I would have to get surgery or something, I was so scared!

All my toenails on my right foot are connected together. I wish i could post a pic... It looks like my Right foot has one toe... My doctor is having me visit a specialist next week.

26 years ago my then 3 year old son was playing, goofing around on one of our wooden kitchen chairs. It tipped and fell. The edge of the seat hit right at the base of the nail on my big toe. The toe swelled, filled with fluid, turned purple, and I was in excruciating pain. I went to the doctor, and he removed the nail. He said I was lucky, it will grow back. He was right, it did. However, it grows out perfectly fine one time, and the next time it grows with a nail on top of a nail. Every nail growth is alternate. Doesn't hurt, never has. Just strange, that's all.

This happened to my big toe in 2008 after going thru cancer treatment. I continue to have it and now also noticed a nail growing underneath a nail on a center toe. Doesn't hurt. Top nail eventually peels off. Have so many other side effects after having head cancer twice now I haven't worried about it. Glad to see it's not just me.

My middle toes on both feet have 2 layers, one will grow under the top pushing the top off from the cuticle area of my nail, after a little time, I can lift the toenail from the cuticle and cut it off piece by piece, slowly until the under nail has grown out completely. I wouldn't recommend "ripping it off" like an earlier post said. In time you can clip the top nail completely away and have a new nail. Problem is if you like to paint your nails, makes it difficult when the under nail starts pushing the upper nail off, looks really weird. Last week something new happened though, my pinky toenail came completely off, just lifted right off without any nail under it. None of the nails hurt but it kind of freaks me out, it reminded me a lot of the movie, "The Fly", when he started pulling his nails off......... WEIRD!!! I'm just worried that it might be a vitamin deficiency and it the toenails are the first warning signs....... ugh! If anyone knows cures, I'm all ears

The second toenail on the pinky toe is actually called a lister corn. I'm 31 and I've had this on both pinky toes for about 10 years. Google "lister corn" and learn more about it.

This is NOT medical advice but my story. Been there done that. The top nail dies. You can wait until beyond the time when it is too uncomfortable & basically grab the end tip of the nail & lift yanking it off hard peeling it off the base. Will be ugly & sore underneath with a tad of blood but wash it off & put an ointment / bandaids over it. Wash well every day & after about 2-3 days you will notice you got an entire clean new nail under it (was there all along). Or if it bothers you before the top nail is totally dead, dig out a corner and basically "LET IT RIP!" pulling it from one corner to the other tearing it off hard. You might have to do each end to get it all & even get straggler pieces the next day or two if you were really early (even “carve” off pieces) but, again, you will find a new thin nail underneath. The question then is did your injury (mine was long distance running) permanently damage your nail bed or a one time thing? If permanent the good news is toe nails grow very slowly but the bad news is you will have to do this again in 3 to 6 months. Note, I am a long distance runner who was always smashing toe nails against the inside of the shoes, blistering all over, sweating, & getting smashed nails leading to double nails. The answer for me has been wearing Injinji 5 toe socks with Vibram 5 Finger Shoes. The socks cushion each toe & keeps the moisture out so you do not blister. The shoes protect each tow. My longest tow next to the big fat one still hits the sneaker base a little but it is much softer material. The Vibram 5s take time getting use to so start slow & build up. They are not for everyone but once use to them they have been my miracle. I got over 450 miles out of my first pair & not a single blister. There is a slight hole at the end of the long tow sockets on each food so there is some friction there but it is much softer material than a regular sneaker. Yes, I know it is gross but I do “LET IT RIP” and I feel wonderful after!

It happens to me too; my second toe is slightly longer than my big toe so at times when I play sports it hits against the front of my shoe a fair bit. It doesn't happen a lot but when it does I notice the toenail is thicker than the rest, grows slower, and has ridges on it.

It doesn't hurt, and to get rid of it I'd try to find a place where it allows me to lift the nail up to separate it from the original nail, and if it doesn't cause me pain (sometimes it'll hurt from the sides where it is still attached to the cuticles) I'll clip the sides away and it will lift off entirely. It doesn't look too gross, just really bumpy looking due to the ridges. The bottom nail will look new and healthy.

Didn't see a doctor because it didn't cause me any pain, no blackening of nail like the other stories so I didn't think much of it but probably will if it starts giving me problems.

This is not big issue. It is common, try to cover it by nail art.
