See a dermatologist: Acne treatment needs months to years. 3 days of anything is of little use. An injection in the cyst may help it, but you need something to control cystic acne. Probably spironolactone is your best chance.

Probably: Cystic acne is difficult to treat and i often find Prednisone for 3 days not effective. Prednisone, in general, doesn't work well long term or short term. We usually start with antibiotics, retinoids and a combo product of benz peroxide and clindamycin. A new product called aczone may also help. Injection may help with one spot not many.
