Question 1

there is a blue/black spot under my big toenail and i don't know what it is. i removed my nail polish today and saw it, and am now very concerned. ?

Accepted Answer

Photo documentation.: A black/ blue spot under the nail in a 16 year old is probably nothing more than a bit of dried blood trapped under the nail. This could be the consequence of a minor bump of the toe of a pressure injury. Without actually seeing it, I guess it could be something else, but I doubt it. To remove all concern, you might  have a physician take a look at it.

Question 2

my big toenail on both feet black and blue some pain what is this from?

Accepted Answer

See below: May be from direct trauma to nail causing bleeding under the nail. If toenails are too long &/or footwear is too short, nail trauma can occur. If u have vascular disease (pad) or diabetes, blood supply to nails may be compromised. See fp or podiatrist for evaluation & treatment options. Make sure nails are trimmed properly & shoes fit properly.

Question 3

why is my big toenail black and blue at the cuticle? it hasn't changed in weeks and i can't recall any serious trauma to that area.

Accepted Answer

See a doctor: My concern here is whether this is a bruise or something else. If you can't recall any trauma or wearing tight shoes, perhaps this is not a bruise. Melanomas can arise under the nail. Please see a doctor for an examination.

Question 4

i removed my nail polish on my toes, that has been on for quite a while, and noticed i have a small black/blue dot on the outer side of both my big toenails. its on the exact same place on both nails. should i be worried?

Accepted Answer

Toe nail: If you do not have any other symptoms and no more spots appear then it’s generally not a reason to worry about. But if you are concerned then please consult a physician and show the dots to make a diagnosis.

Question 5

my one year old son has a blue/black spot on his left toe nail. it has been there for like two months.

Accepted Answer

Bruise: He likely hit his toe &amp; accumulated blood beneath the nail. When this happens it takes a long time for the stain to grow out. Kids toenails grow at 1-2 mm/mo so it can take quite a while for it to move to the top &amp; allow you to cut away the stained part. It is not a reason to worry.

Question 6

7 weeks ago i had pereneous tendon surgery and my foot has severe swelling and incision has dark blue/black line.  is this normal?

Accepted Answer

If you were healing: well and you suddenly have marked swelling - I would advise your podiatrist or orthopedic surgeon.

Question 7

what causes  black and blue toenails?

Accepted Answer

Trauma: Usually trauma or injury will cause bleeding under the nail and the appearance of being black & blue.

Question 8

what does it mean when your toenail turns black and blue?

Accepted Answer

Trauma to toenail: It usually is indicative of a traumatic event to the toenail.  The discoloration is a sub ungual (beneath the nail) hematoma.

Question 9

what's the reason why my toenails are black and blue underneath?

Accepted Answer

Rubbing in a shoe: If you are runner this is a common occurence due to pressure with the nail and the shoes.  We call this runner nail.  If you are a runner or not seking medical attention to have this evaluated will be a great help to prevent this from happening again and again.  Go to www.Myfootandankle.Com for more information.

Question 10

both big toenails discoloured, blue looking; right one particularly looks as though black streak in it. slight pain but nothing major. what to do?

Accepted Answer

Microtrauma: It sounds like your toenails are hitting the end of your shoe.  This usually happens if the toe box is either too small (toe is pressed up against the end) or too large (foot is sliding around and the toe is hitting the end).  This is very common in runners--it can lead to either thickening of the nail, or it may eventually turn black and fall off--a new nail will grow in within a year.
