Hi my fiancé has a lump on the back of hear earlobe that is full of blood (deep red and a tinge or yellow in colour) we know this because we popped it. It is weeping at the moment and we would just like to know what it is. Keep in mind that he was diagnosed with cystic acne but since being on roaccutane for 8 months 2 years ago it had appeared to clear until now.. Could this lump be his acne?
