had a mammogram and now sent for ultrasound

Hi,
so..30 years old and by luck discovered a lump in my breast which is quite painful.  Went to the doc, and she said it was something that should be further investigated and estimated approx size a little over 2cm.  have not seen mammogram results but i have been booked now for an ultrasound that is to be performed by a doctor who specialized in it? not just the technician..is this normal or???
anyway this lump..cyst whatever it is painful and pain is still here, have now notice hte lump and painfor 5 weeks and pain is the same if not worse. have never before expereince any breast pain whatsoever.  when i go to sleep on my stomach well it hurts and pain is throbbing at times and shooting pain at other times.  in the past week i have noticed a change in size/or shape not 100% sure, and looking at hte the skin where i feel hte lump is a little discolored and can actually looks like i can see 3 veins that are slowly becoming 3-d'ish and can feel the slight non-smoothness there. nothing crazy but at least was not like this before, any takes on this???

A Radiologist is always present when Ultrasounds are done. They are read then and the Radiologist then speaks to the patient. A lump due to breast cancer is rarely painful.
