Help!! did mammogram and was normal. no ultrasound done. still have pain. feel something hard. what to do?

Clinical breast exam: Have you had your doctor do a clinical breast examination(CBE)? A mammogram should always be accompanied by a breast examination done by a health care professional as the mammogram will miss 10 % of breast lumps. if you and your doctor feel a lump, it must be checked further with an ultrasound and a biopsy of the lump is also a must if the lump is confirmed by your doctor
