 [ Symptoms ] if there is a person in your family who has h1n1 virus how long should we as a family stay quarantined [ Disease ] i am sorry you are experiencing this the fact you are experiencing this in both nipples actually could be a good sign because breast cancer does not usually arise in both breasts or nipples at the same time so you can probably put your mind at ease about that aspect of things although the sensation feels like a deep ache  you might be suffering from dry nipples you can try keeping your nipples moisturized with a good hand lotion to see if that helps if you do not get relief from moisturizing i would suggest you consult your primary health care provider to rule out anything more serious hope this helps
