alescursedmummy, I am so with you on this and it was only last week I had the all clear on mine.
In 2000 I had a benign breast lump removed. But until I was 100% sure it was benign I wa in a black hole. At the time my children were very young and I just thought of the worst case scenario. - how would they manage without me.
Since then I checked my breasts almost daily. It became a totally irrational fear of mine. My boobs also became very sore and tender, like your, with pain etc. I've since realised they change with age, hormones etc and pain can actually be a good thing.
I was so bad that if i felt no main lumps, the world was fine, but if I had a feeling there was something there (around the time of a period for example when they became lumpy) I was on edge for a week until the lumpiness subsided.
I regulary went to the docs and their examination would put my mind at rest.
Anyway, 2 weeks ago I found a definite lump, something different from usual, which is what they tell you to look out for now.
The doc said she was sure it was an OK lump as it was 'mobile' but she could see how anxious I was and because I asked her, she referred me to the breast clinic.
That week I went into a black hole again, imagining the worse.
I had a phone call the next night telling me they would see me in 7 days.
I broke down in the clinic, through worry. I had a mammogram and ultrasound which clearly showed I had a cyst. I had lots of them actually but the one I could feel was nearer the surface.
I asked the consultant if he would remove both breasts as I couldn't stand the worry I go through. I felt that bad!
Now I'm back to my more rational self, when I return to the clinic next week to have the cyst drained I'm going to ask if I can have a yearly mammogram. I think the consultant could see this is a big problem for me so we'll see what he says.
Anyway, really just told you all this to let you know that someone understands what you are feeling and now I have my rational head back on, 9 out of 10 lumps are benign and worst case scenario, if caught early, this horrible disease is treatable.
Hang on in there to your appointment. Your gp would have indicated if she were worried. It's probably a cyst or one of those fibrodaema thingys. x
