I have something almost identical going on. I had a mammogram back in January which was clear but I just felt something wasn't right so I went back to doctor and she referred me again. They did a second mammogram which is showing changes since January. I had an ultrasound and biopsy yesterday. They said there was a lot of fluid on the breast and that it may be either a cyst or infection. I have a ten day wait for biopsy results which is going to cause anxiety but I'm glad I trusted my instinct and went back. They told me they see all sorts and they have had a lot of unusual cases since Covid. Wishing you all the best for a good outcome. X

Hopefully you won't have to wait too long. It's good to have someone to confide in though if you can. I've only told a couple of people myself but it has helped a bit
