Its posibel that your fibroidesis usually are moveable and you feel breast pain because may be is the rubbery nodels that cause painfull swelling near the breast surface. You must to do : • Mammography which is the method for the detection of breast fibroids . • Ultrasound examination is quite helpful in this case. • Also my advise is to do biopsy and aspiration of the breast (its an accurate diagnosis and to differentiate between breast fibroid and breast cancer About your questations if :Can treatment for breast fibroid and hypothyroidism go together?Are some hormons that influence the development of the berast fibroids:Thyroid hormone(hypothyroidism)Prolactina, Insulina, Growth factor and very important : • Are the monthy changes in level of estrogen and progesterone .
