Hi mountain - a bit late into this thread, but only just tuned in....
I'd been having the same symptoms for more or less the same time as you have & saw my gp two weeks ago for an examination.
Thankfully, she told me she couldn't feel any lumps in my breast or under my arm, but recommended I start taking Evening Primrose Oil capsules to help alleviate the discomfort, which I have. I must admit, it does seem to have helped, coincidence maybe, but it has.
If the second opinion is the same as the first, maybe you could try Evening Primrose Oil capsules too -you never know......
Good luck.
