I was initially thinking of inflammatory breast cancer when I asked you those questions, but seeing as you do not seem to have other symptoms of it I don't think this is what is going on. Obviously a physical exam would be crucial here. . .but a couple ideas I had:
1. Make sure your bra is properly fitted. Sometimes an improperly fitting bra can actually cause breast tenderness
. You can even be fitted for free at places like victoria's secret.
2. My guess is that you are not yet post menopausal and likely still experience hormonal fluctuations throughout the month. Sometimes breast tenderness can be increased by this. Additionally, if you have fibrocystic changes in your breast, caffeine consumption can worsen the cystic changes and make it quite painful. This could be contributing as well.
3. Sometimes hypothyroidism leads to retaining more fluid. The breasts are sensitive to fluid retention and can sometimes feel swollen because of this.
4. You are correct to check for discharge and moniter for skin changes. You are doing all the right things, especially considering you had a mammogram recently. This is reassuring. That being said, if the symptoms persist for another couple of weeks please have a doctor check it out as well. Usually whole breast tenderness is not as concerning as just one specific spot (but again, that's just a generalization).
Take care. I know you are worried, but you really are doing a great job checking all the right things and keeping close tabs on your breast health. Follow up with a physician if symptoms don't resolve in 2 weeks or you develop any of the above symptoms we mentioned (skin changes, pain in one specific spot, discharge, fever, etc). Please click accept for my time. Thanks, ***** *****
