Anybody had pain in her breast area with herceptin??

Hi there

I was wondering if anybody had pain in her breast or tumor area when on THC ot Hercceptine????

I am doing chemo before surgery, i did have 4 rounds of FEC and after a chest CT it showed that the tumor is gone , i had pain in tumor area with FEC and i was thinking it 's a good sign of killing the tumor , the onc confirmed that too , now i have to do 6 round THC and weekly herceptin in between and since then i have even more shooting pain around my bad breast (right). Sometimes it's under the breast and its scaring me about my liver , I had a clear pet and ct scan when diagnosed and right after we started the chemo which shrank my tumor , i was thinking may be there are cancer cells in my liver and the chemo is working on them or may be something is growing in there??? I had a chest CT scan couple of weeks ago and that was clear and even the tumor and lymph nodes were clear with no sign of cancer. I just wanted to know if anybody experienced this kind of pain ?
