Breast Pain

For about 3 months I have been experiencing pain on and off on my right breast. I thought at first it was to do with my bra being the wrong size as it's where the wire is. So I have been remeasured and have new bras. It is a stabbing pain which for the last 2 weeks is now there permanently. There is no lumps or changes to the breast or nipple. I went to the doctors yesterday and she also couldn't find any lumps etc.
She is now sending me on a non urgent appointment with a consultant. Which I'm happy with as I don't think it's anything serious. In the past I was diagnosed with breast grissle on my left breast.
Has anyone else ever had anything like this.
