Thanks for posting your query.
I have seen the photographs posted in your profile.
From the his
tory that you have provided it looks like paronychia of the nail which progressed to infection of the fingertip. Paronychia is
a soft tis
sue infection around a fingernail that begins as cellulitis
but that may progress to a definite abscess. It is
of two types: acute caused by bacterial infection and
chronic caused by fungal infection.
