Thanks for responding, Winged!
I did a search under "underwire bras" on the web & found some interesting info.
[url="http://www.strategicjungle.com/kathleen/1025bkk.html"]www.strategicjungle.com/kathleen/1025bkk.html[/url] is one site where a health watch reports about a study linking breast cancer with underwire bras.
Also Dr. Sydney Ross has written a book called "Dressed to Kill" showing the relationship between bras & breast cancer.
Dr. Christine Northrup MD says to "stop wearing an underwire bra. Too often this kind of bra cuts off circulation of both blood & lymph fluid around the breast, chest wall & surrounding tissue."
Dr. Jesse Hanley, MD says "not to wear underwire or even tight bras because they block the lymph glands under the breast. Lymph glands play an important role in draining toxins from the breast."
I found all this interesting.
Thanks for your concern. Today the pain is subsiding & I am beginning to believe it may be because I haven't worn an underwire bra since the day I went to ER (almost a week ago). Coincidence? Maybe, but then again, maybe not!
