Inverted nipple

Hi

looking for some advice from others that may have similar symptoms. 

About a month ago my breast was very swollen and hard, this passed in around a week and I didn't think any more of it.

Then last week I noticed my nipple has started to invert on the same breast. It inverts more when I place and pressure on my breast. I went to the gp and they sent me to the breast clinic.

i had an ultrasound which showed no issues, however the doctor was not happy with the way the nipple looks and so wants me to come back in 1 month and to have a mammogram.

just looking to hear others experiences and if anyone has experienced similar symptoms?

thanks
