Has anyone experienced bruising on their stomachs after work outs? I just started at the gym after many years away... I started running on the treadmill and I've been sore all over but today I noticed bruising on my flab.... (I'm pre op) I think my body is going into shock lol Anyone experience this? Should I call my surgeon or my primary??

How bad is the bruising? You may have just slightly hit it or something and it bruised a little. This happened to me like 6 months ago where I had this HUGE bruise on my stomach when I woke up one morning (no idea what happened) and gave myself a slight hematoma. My Dr said the more fatty tissue you have, the more your are prone to bruising it or causing a slight hematoma even with the slightest bump or hit or whatever. Im sure you will be fine. If it gets bigger or worse then id contact your primary.

I get bruises from dumbbells when I'm getting in to position for dumbbell presses, and from my belt during deadlifts, never anything from just running though.
