Might it be possible that a a diuretic like furosemide causes breast tenderness on a 77 year old man?

Is there Spirono?: 140 of ~90, 000 people taking Furosemide reported breast tenderness. This is just over a 1/10th of a percent and isn't really different from the number on placebo reporting the same. However, a medicine called spironolactone, commonly prescribed with furosemide, does frequently cause breast tenderness, pain or swelling. Does this pertain to your situation?
