Spot that won't go :( help

[handle1]

Hi
I’m a 45 year old woman and have a persistent spot on my cheek. It won’t go! I’ve had it for around 2 years :(
I’ve tried lots of products, had facials,extractions, milia removal but this one spot won’t go. Been to doctors and got referred to dermatologist in hospital and she said I had mild acne and prescribed me Lymecycline and Epiduo gel. I’ve been taking both for nearly a year now. Skin better but this spot won’t go!
It’s sometimes gets pus (sorry yuck 🤢) in it but doesn’t feel like there is anything in it.

Any advice would really be great !

It's gets me down :(

Hi, you should ask to have this checked as it could be a BCC. It's easily treated but may need to be removed. Find out which doctor at your surgery specialises in skin conditions and tell them you'd like it biopsied. 2 years is a long time and it should've healed by now x
