Periductial ectasia???

Hi 

Two years ago had swelling inverted nipple lump under arm and pain. Got referred to the breadt clinic where they done a scan told me I had periductial ectasia and a lump due to smoking awas given antibiotics and told to stop smoking.

I quit smoking for a year and a half and started smoking again (stupid I know)

Quit in January on champix.

Iv now got a painful breast with a inverted dented nipple  no lumps or redness a painful chest like muscle pain and a sholder back pain that feels the same.

I turned to “Dr google” today and now I’m convinced I have a tumour I have sent my anxiety though the roof. I now have a gp appointment on friday.
