Looking for advice

Hi I’m looking for some advice about changes I have noticed in one of my breasts,

my nipple has been itching on and off for quite a few weeks and my breast looks larger than the other I keep getting a burning / stinging sensation behind my nipple and I have noticed at least 6 blue veins all going to my nipple one comes from my arm down my breast and around the nipple I have a dull ache in my back where my bra strap goes and an ache in my collar bone I visited my doctor yesterday and she said the veins are due to my periods but I said I had a hysterectomy 5 years ago she then said its sometimes normal to see veins like this then I was told I must have banged myself and to take pain  killers for a week 

should I take her advice or seek a second opinion ?

thank you from Joanne age 43

waiting a week is probably fine, but if things don’t improve go back, and if they get worse go back. Itching and swelling are both symptoms to take seriously. It is probably something minor, but its not worth gambling on that… If she is not more help next time I would ask to see another GP…
