bruising on breast after infected cyst.....

Hi there

Does anyone know whether bruising on the breast can be due to anything other than IBC?

I had an infected cyst on my breast before Christmas and after 3 courses of antibiotics, the last a stronger one, it finally responded. It seems to have left a pink circle with a blue squiggle inside on the breast…

I am worried this may be a sign of IBC or can there be bruising/scarring as a result of the infection?

Anyone who could tell me of their experiences or help would be so grateful for some input.

Thank you
