Is it normal to get a follow up appointment ? 

So I had an appointment at the breast clinic on wednesday. The Dr that saw me was pretty dismissive when i showed her the patch thats been bothering me on my breast ( red , raised , dimpling) To be fair at the time it wasnt as red or as raised as it normally is but I told her it comes and goes and you could see the difference to me! She said it all looked normal and these things are normal after pregnancy ( 9 months PP ) and felt no lumps but sent me for a ultrasound  for my "own peace of mind" 

when I had my ultrasound the patch was super raised and red and i told the lady scanning me that it comes and goes and i was trying to explain that to the doctor but it wasnt as red ar the time, she said she could definately see that my skin was thickened on one side and she'll tell the doctor but everything else looks good no lumps or cysts and that maybe there was an infection at one time but its not there now! She said after that doctor ( without seeing my results) said I could go straight after

I left thinking a little confused but happy that they were saying im fine but now im worried that they've found something or maybe just want to investigate why the skin has thickened?? not sure but im worried again  

The appointment is march 3rd so i have another month of anxiety
