Im quite concerned with lumps in my earlobes, originally I had a lump and it grew and grew but eventually exploded with pus and blood, it was very painful. A few months after the lump returned but was smaller, I decided to goto see my GP this time who prescribed me with some antibiotics, they appeared to work as the lump disappeared during the course, again the lump keeps returning but the strange thing is that it appears to jump from one ear to the other Im sick of popping pills and it coming back and now its starting to worry me, I dont want to keep going back to the GP to be fobbed off with antibiotics when the problem still hasn't been adressed, what is causing these lumps and what are they exactly, is there any chance it could be something more serious as someone told me your ears and heart are somehow connected.

Any advise would be deeply appreciated, thankyou
