Hi,
Speak with your doctor about this. You might also want to research online, 'Menopause Symptoms After Hysterectomy' ~ there are some women who experience some or all symptoms of menopause post hysterectomy. Consider speaking w/your doctor about treatment options for this. I have not had a hysterectomy, but I am going through perimenopause and have dealt with very painful breast. For breast pain and tenderness, I use a warm compress (washcloth works fine) applied to the painful area's and also I take an ibuprofen or aspirin for more relief. Stay away from tight fighting bra's/clothing during any tenderness; you might want to go braless or wear a cotton sports bra when you can.
~ Hope you feel better soon :)
