Stupid rash

Hi all, I am new to this forum, but have been reading it for about a week. My story begins about 3 months ago when I was in the middle of a family crisis. I was also having delayed pressure hives quite severely. One Monday I was rocking my 3 yr. old grandson and had his head resting on my right breast for quite awhile. The next day that same spot had a rash about the size of a dollar bill folded in half. I thought it was a pressure hive. It lasted a few days. faded away with a small bruise like spot and was gone. I thought nothing of it, not knowing anything about IBC. Fast forward to last week, again I was watching my grandson and by the time he went home I felt like I had been through the mill. I'm 68 years old and he is tough on my body. I was lifting and carrying him against me and rocking him...etc. The next day I was changing my shirt when I noticed both of my breast were bright pink. The right more than the left. I immediately called to see the doc and went in the next day. Since then, the red has subsided from the left breast entirely and has shrank into a light almost not noticeable spot the size of a small butterfly. It also has a microscopic bruise as it fades. Almost the same place as the first spot that I though was a hive. My doc has scheduled a mammogram tomorrow as I am due, but he also has scheduled an ultra sound right after at the hospital so there will be a radiologist on hand to interpret. I would also like to see a dermatologist this week if possible for a couple of punch biopsies. This is a horrifying experience that I wouldn't wish on anyone.....sound familiar???
