Skin Thickening

I have developed over the last couple of years skin thickening of my breasts and abdomen, only one side of my abdomen.  the entire area has no feeling, its like this huge ball of nothing.  When i try to exercise, IT HURTS.  when i walk too long, the pain gets intense from it pressure of it hanging i guess. When i wear a bra for a long period of time, it will aggravate the areas of my breasts and when i take the bra off, the pain is soo intense.  it will eventually go away, but when it happens, it is soo intense.  i had a mammogram and it showed areas worrisome for inflammatory CA, so my doctor sent me to a doctor to get a biopsy, he looked at it and said ohh everyone is overreacting, you dont need anything, go home.  The skin has an orange peel appearance, just like in inflammatory CA, but i have no other symptoms of it.  And it does not neccesarily get bigger.  It does have a sensation of itching occastionally.  

please help with any other ideas of what this may be and what potential complications there could be.
