Lump on breast

Kristi

Hello, this morning when I woke up I saw I had a red area on the side of my breast about the size of a fifty sent piece and there is a hard tender lump. I’m not sure what it is or if I should wait a couple days and see what it does? We were camping and I got bug bites, but this doesn’t look like a bug bite and I don’t see any bite marks either. Do you think I should go to the drs right away or wait a little? Thank you
