I don't usually get pimples. Two months ago I had one pimple on my cheek, I ignored it and it turned into a big white one. After some days it shrank and I popped it. It again grew into a white and then in few days shrank into red spot. This red thing is not disappearing. Tiny pimples also started coming and disappearing now and then. I'm also noticing pores on my skin and the texture of my overall skin is changed a bit. Two weeks back I started applying bdiff gel. Before that I took (tretiva 5, cnn 100) for 10 days as my doctor recommended. There is very little difference in the pimple/spot if you look closely but it's the same. The rest of the skin is looking better though. Should I take the tablets and gel together? Any other recommendations? What kind of stubborn thing is this pimple. I've never had anything like this before!
