I seem to be having 2 different types of lower back pain. One is when I am doing a rising trot - every time I rise, my lower back cramps up. Sometimes it is right at the pelvis, sometimes it's the area on the left just above my pelvis (I think it might be the psoas, which means I probably just have to strengthen it...Here's some info about that muscle: Psoas major muscle - Wikipedia, the free encyclopedia )
The other thing is I suddenly have this pain in my tailbone that feels like nerve pain. It's pinchy and kind of burns and it's like someone is holding a lit match to my tailbone constantly. It started after I had a lesson where I did a lot of sitting trot, and I'm thinking it might have been the cause of it. That same lesson, I cantered for the first time in a couple months (I was out for a month because of a concussion and then was building back up to being able to canter).
I think these are two different things. The lower back pain is probably my pelvis being out of alignment and being weak. I'm guessing. The tailbone thing...It really feels like nerve pain because of the pinching sensation.
Has anyone else ever experienced this, particularly from a rising trot or canter? Thanks :)
