Had a boil now left with a open hole

im very prone to boils on my inner thighs due to having chunky thighs that rub together but this time its left so type of open sore/hole. is this anything to worry about ive applied sudocrem on to
it as a barrier but not sure if thats safe! really panicking and dont know if going to my GP is needed

Sodium Hypochlorite 6% for a minute and rinse. Do it every other day and then 3 times
