Been there, done that...it tanks. Sorry to hear about the bruises. It took me a long time to realize that I needed shorter stir ups. I thought my saddle was just uncomfortable but then I shortened my stirups for a kid to ride one day and hopped on after them without adjusting them and I noticed that my saddle fit me better.
**LIGHT BULB MOMENT** I was supporting myself solely on my tush and with the shorter stirups my pelvis was rocked back just enough to put me on my seat bones instead of my pelvic bones, like I was riding on my back pockets more.
Now I adjust my stirups so that they are about ankle length with my feet out of them.
Hope you get to feeling better soon and Welcome to the Forum!!!
