Painful right breast

Went to see gp last week , she examined me whilst I sat on edge of bed not lying down . She said she didn't feel lumps but gave me antibiotics saying it could be infection!

they have not helped in fact it is more painful .

I have asked for another appt so will see her on wed .

in meantime I can't sleep eat and feel nauseous .

my anxiety is through the roof . I am 72
