if you feel you may be hypothyroid it wouldn't be a bad idea to get checked out. if you do have hypothyroidism you should be treated for it. breast tenderness generally isn't considered a symptom of hypothyroidism but it can be a symptom of other hormonal changes or imbalances. some women complain of breast tenderness during perimenopause or menopause and they also discover they are hypothyroid at that time. so it can appear as if the hypothyroidism and tender breasts are linked when they aren't necessarily in a clinical sense. your best bet is to make an appointment for an evaluation by a health care provider particularly since you said you have a lump on or near your thyroid gland. hypothyroidism can be treated and the sooner you catch it the better. best to you!
