Do not put chemicals on your skin that are not intended for skin care. Serious injury and permanent scarring can result.
If you can get in to a dermatologist that fast, some of them will 'extract' the fluids from a raised blemish and apply something to take down the inflammation. Most insurance will not pay for that. The dermatologist will also treat you on an ongoing basis so that you do not need a 2-day cure in the future.
Dermatologists have a great variety of treatments to offer, and will work through the treatments with the least side effects and expense first, but will almost certainly arrive at a treatment that works for you.
