Hello I am 26 weeks pregnant, I sometimes work longer shifts (11hours) but only once or twice a week. The rest of the days I work on average 6-7 hours each day. I get either little or no time to sit down while at work to get off my feet, even for a minute, except when I work the 11 or 12 hour shift; I get some time then. Anyway, my feet are so sore lately and all around my heels are dark purple, they look bruised and swolle and are sore to touch... is this common or normal??
