There seems to be no cause of alarm here. I suggest you relax and stay calm.
Fibroadenomas are the most common cause of breast mass in your age group .They are caused by fibrous and glandular changes in the breast and are affected by hormonal changes in the body.This may explain that most of them enlarge and become painful in the menstrual cycle or may recede and disappear in due time. Fibroadenomas are usually solitary but they may also be multiple.They may also enlarge and cause pain.
Taking OTC analgesics may relieve the pain caused by the fibroadenomas.However, push through with your physician consult for further evaluation. I feel that you are highly anxious and the lump causes pain and discomfort.A biopsy may be done for a definite diagnosis of the lump and also to allay your fears.
Is there a strong history of cancer in your family?
