Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns....
As per your complain the discolouration and bruising of the nail is due to
injury leading to ruptured blood vessels..
There is also a possibility that there is detachment of the nail due to trauma..
Nothing to worry as gradually the healing will take place.
As of now you can do cool compresses around the toe nail..
You can also take
Motrin or
Aleve if there is pain..
You can apply an antiseptic ointment over it and cover with a bandage to prevent further injury..
If the nail seems detached apply a numbing gel containing Lignocaine over it and gently cut the broken nail off..
In case if it does not show signs of healing in a week or if the symptoms exaggerate consult a General Physician and get evaluated..
Hope this information helps..
Thanks and regards.
