boa shedding problems/nose burn

[aj099]

hey guy`s thanks for all your help with my python

ok so here is my question ,
my boa alice is having some shedding problem`s
usually she shed`s very nicley always one peice shed`s
take`s usually 3 day`s from blue eye faze
since her last shed about a month ago i think she burned her nose
it is a black spot that look`s to be a burn but maybe is from rubbing
i have been puting a small amount of polysporin on it
and now she is having problems shedding she went into blue eye faze
about 6 day`s ago she is clear eye now skin look`s rough
with parts of it coming off i put her in her new cabinet inbetween this
because i wanted her to have optimum heat and humidity she is loving it but still has not shed.

so i soaked her in a warm bath with a towel in the bottom for about 30 mins to 1 hour and put her back in the cabinet and it has been about 4 hour`s and still no shed
please guys any advice you can give would help

thanks alot!!
