welcome to healthcare magic
from the description of symptoms yes it could be an infection usually fungal in nature, a cream with antifungal, antibiotic and steriod
it could be also itchiness due to friction and heat produced due to wearing of pads a steriod cream could also help.
you should get a urine test done and if have a discharge get a high vaginal swab
done to know whether bacterial or fungal infection
hope to have answered your query.
wish you a quick recovery.
