My girls are 6, 4 and soon 2. All c sections. Epidurals with all 3 and spinals with first one. 2 months in a row (not sure how long its been happening before this) hubby noticed a bruised mark on my back. Size of a pop can and it surrounds the area where spinal and epidurals were. I have always had back issues but has gotten worse with kids. Mysterious mark seems to appear a few days before my period. Not a typical black and blue bruise, but dark red dots. No bruise in center of the mark or top and bottom. Basically along the sides as if it were making a perfect circle.
