Hellos, I ve had acne for a while and gone through numerous antibiotics, for the last 6 months I ve had a purple lump on my cheek which feels soft like there is liquid inside, prior to this orginally there was a spot there filled with blood, a few weeks ago I got given antibiotics to make the lump go away which the lump reduced but the purple still dark and noticeable, the last few days the lump became sore and uncomfortable so like most people I reached for the nearest needle snd popped the lump, scarily the spot poured with a stream of blood and pus which seemed to leak for around 5 minutes , what s causing the purpleness? Will it ever go away?
