Where to begin.....

I recently had a mole photoed and sent to the dermatologist, so it was a case of wait for the results type thing, so whilst I've been racking my brain hoping someone will ring me I found a lump just under the mole but deep inside the tissue. I never noticed it before but whilst I was washing in the bath I happened to put my arm over my head and my finger brushed something so felt it and there was a distinct lump there (had my partner check as didn't want me imagining things off the stress of waiting for the results of the mole) anyway I rang the doctors about the lump to which he told me the mole was being classed as some kind of infection and they were putting me on steriod cream for the mole and anti biotics (I know in my heart it isn't an infection) anyway fast forward to going to get the prescription I've been going for 4 days and it's still not in and I'm worrying because I just want them to see me to feel the lump and put my mind at ease but he said to just 'wait' I'm going out of my mind now as I can feel it there and just want someone to talk to me about it....a little bit of reassurance goes a long way xx
