<s>[INST] Hi im concerned and in pain... my nipples have been erect for three days. the nipple is sore and tender. I am not on birth control and I am not pregnant. I am 40 years of age. I cant tell if its period related because I had an endo ablation in july... I have never had this before. there is no discharge, no other symptoms. my nipples are just erect and in pain... how do I deal with this? thank you [/INST] Hello, I have studied your case with diligence.There is possibility of benign lump or abcess in your breast leading to erect nipple.I will advise to consult your treating doctor for clinical examination of breast and then we can do required investigation.Mammography and ultrasound may help for detail diagnosis.So I will advise for clinical examination and as required MRI spine screening, and cardiac investigation.Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health.Take care </s>
