Pain after treatment

Hello!

I was diagnosed with stage 3 IDC last April. By May, I had a lumpectomy which turns out my Margins weren't clear and also the two sentinel nodes were also cancerous. Wondering if another lumpectomy was worth it, I asked my surgeon if there was anything we could do to make sure we get everything at the next surgery, and if lumpectomy was still the right choice. She sent me for a breast MRI. Turns out, I had two additional tumors in my breast, and a fibroadenoma in the left breast. In July, I opted for an mx of the right breast, and she also did a full axillary dissection. I had 2 additional nodes that came up as cancerous. 4/19 total. I started chemo in August - 4 ac and 4 taxol. Immediately after, I did 31 rounds of radiation. Now I am on aromasin and Lupron to shut my ovaries down ( I am 27). My worry is that I continue to have breast pain and armpit pain similar to the pain that sent me to the doctors originally. What should I do? I have voiced these concerns to my oncologist, she said she is not worried, but I am. She also palpated to see if she could feel any lumps, but nothing. It worries me a great deal because even with 3 tumors and 4 cancerous nodes, the only thing that was able to actually be felt was my original tumor. Please help and give me advice! TYIA!
