When I first stared accutane I had a bad flare up with lots of nodules/cysts, my derm put me on prednisone and antibiotcs for 1 mouth , now 90% of my nodules/cysts are gone , but not gone for good , they somehow entered my skin,if i put my hand on my skin and push i can feel it and I have redness on the surface PIH I think..what to do?
