Breasts pain can get worse with changes in your hormone levels or changes in the medicines you are perhaps taking,particularly if you are receiving HRT (
hormone replacement therapy).Stress can also affect breast pain.
As a rule,women who are 40yrs old,should have regular mammograms or other test that the doctor may recommend.So, please make an appointment with your doctor(preferably a Breast Specialist) for a clinical breasts exam.
Take care and best wishes...
