I am 45 year white/Mexican female. I have pain on what I believe to be..breast bone? At times feels swollen and painful. Also feel tightness between my breast and rib cage area more to the left side..It honestly feels as if there is something is under and pushing on my left ribcage area. Feels like I need to go up a size in bra..Pain also down the center of belly area and also the lower left abdomen. Pain in my back again, more to the lower left about even and just below bra area.. also constipation and frequent yeast infections..not sure if related.
