Hi, I had 3 biopsys in Oct after I found a lump. Several weeks later had all clear but now in Jan I've become very sore in the bit between my boob and armpit it's tender to touch, I can't feel any lumps and I don't think jts swollen but I am a little worried, should I give it some time to see if it just goes away (it's been about a week since I noticed it and it's a little worse than when it started)
