Hi - This could be a simple infection – mastitis. You can develop mastitis at any time, it doesn't have to be as the result of breastfeeding. This could also be a sign of a rare form of breast cancer, inflammatory breast cancer - though at your age, and given the rareness of this diagnosis, it's highly unlikely. But either way, if this lasts longer than a few weeks – and certainly if it gets worse – you need to go to the doctor to have it diagnosed and treated, if necessary. Good luck - PJH
If it is right before your period, this could be hormonal; however, usually hormonal swelling and tenderness are on both sides. If it is the week before your period, you could wait to see if it gets better afterward. I wouldn't wait too long to see the doctor. As PJ says, infection or inflammatory breast cancer are possibilities for these symptoms, so waiting too long is not a good idea. Both infection and IBC also usually include redness and other symptoms, so you'll need a doctor to help you figure out what is going on.
The big difference between Inflammatory Breast Cancer and Mastitis in it's early presentation is ... Do you have a fever? A fever is present with an infection, but not with IBC.
It's been almost 3 weeks since you first wrote in to this group, so a breast specialist "Who is FAMILIAR" with IBC should be your first choice, IF your breast is still swollen at all (and you had no fever when this started).
Just stay vigilant.
I am 32 years old. I have had very severe pain in my left breast for over 2 weeks. Went to about 7 doctors until one of them finally gave me Danazol. The pain in my left breast is much better... infact almost gone, however, the left breast now feels fuller and looks a bit swollen. I keep going back to my family doctor, she keeps doing physical examination of my breasts and she can't feel any lumps. She ordered an ultra-sound and nothing came up on the ultra-sound. I have not had any fever throughout all this. She referred me to a Breast Clinic but my appointment is not for another month in the meanwhile, I don't know what to do.
