Hello and welcome to HCM
Appearance of blisters on toes and bruising under the toe nail indicates irritation and injury
of that area.
See to your shoe fitting.
An ill-fitting shoe can cause such problems.
If you need continue walking then see to your shoe fitting.
Change to a good fitting shoe or get such shoes which do not cover your toes.
Let the blisters heal on their own and do not squeeze them.
Squeezing can cause super-imposed infection.
The brusing under the nail will clear away with time.
Thanks and take care
