Right breast & armpit pain

Hi, over 2 weeks ago I woke up to find a small red mark on my right breast & then I felt some breast ache.

The following day the red mark had faded but as the days went on I developed armpit pain, arm pain & shoulder pain all on my right side. Plus I still have the breast ache.

Of course  I googled & came up with inflammatory breast cancer. 
 

Now the breast mark has practically faded. I cannot feel any lumps in my armpit or breasts but my right armpit does feel slightly swollen but when I got my sister  to have a feel she said it didn't feel swollen. 
 

No other symptoms. Not on any birth control, not on my period & no history of breast cancer in the family. I'm 40.
 

Im trying to get a Drs appointment so just wondering if anyone else has experienced this at all & what was your outcome?

Any responses gratefully received. 
 

Thank you.
