Any Input Please...Lump and Constant Pain in Left Breast

I have posted in the "Not Diagnosed but Worried" category with no response... I am just looking for anyone who can comment, give advice, etc.

Aside from a few days here and there, I have had constant left breast pain for 4 months. There is a small lump. It's at about 2 O'clock.  I have been told by 2 doctors, 1 breast surgeon and 1 radiologist that it's nothing to worry about. What worries me is that is just showed up all the sudden...

Here is my story:

I am 25 years old, with no known history of BC in the family. The night before Easter of this year, I was woken up by pain in my left breast when my cat stepped on me. I didn't think much of it, but when I felt the spot I noticed a lump. I made an appointment at my gyno right away. I saw a nurse practitioner. After feeling the lump and seeing how much pain I was in, she told me it was probably a cyst but sent me for an ultrasound at a breast clinic. The radiologist told me the lump was a "swollen lymph node" and there was nothing to worry about. I questioned him - so he found another lymph node on my neck and tried to show me that they looked the same on the screen - which I did not agree with.

From there, I waited until my annual appointment at my gyno, which happened in June. (This time I saw my usual doctor, not the nurse practitioner.) I told my doctor that I was still in a lot of pain, and the lump was still there. When I say pain, I mean anything triggers it. Hugs, rolling over in my sleep, leaning against it...God forbid I ever take a soccer ball to the chest. Anyways, she told me she wasn't concerned, but sent me to a "well known" breast surgeon for a second opinion.

I saw the breast surgeon in early July. When she took a look at my ultrasound, she said "well, not much to see there," and said she didnt see anything weird, abnormal or suspicious. In fact, she said she couldn't even feel the lump, and I was like really? And she said "Yeah. Both breasts are just lumpy in general." She told me that I probably just have painful breasts, which can happen to many women, and to reduce my coffee intake and take vitamin E and evening primrose oil, and wants to see me back in 6 weeks. She also said she doesn't think it's the lymph node (which is what the radiologist saw on the US) that is causing me pain. Needless to say I was pretty disappointed with that "answer."

After 4 opinions and an ultrasound, I am still not satisfied with the findings. I have a strange feeling that all is NOT well. If there is nothing wrong, why am I in so much pain?

What the pain is like: As I said, it's worse when it's trigged (knocking, leaning, hugging, rolling over) but there is also a generalized pain that is there most of the time. Not severe, but just enough to be annoying. It's a tender soreness type of pain.

I just worry that I am being brushed off by the doctors because of my age. But things like this are taken seriously at any age...right??? I don't know what to do now. Demand a biopsy...mammogram...removal? Just wait for my follow up August 27th with the surgeon?
