Hello, after not riding for two months I managed to get back riding and continue my lessons but in the middle of rising trot not long after coming around the comer I slipped of, I think that due to the fact that my saddle slipped sideways that my girth wasn't tight enough as I lost my stirrup and then the next second I am on the floor with the wind knocked out of me, I landed on my side in the sand arena. I wasn't injured but I am wondering what pain I will be feeling the next day, as I am already a bit sore from the hour lessons and some of my mussels are sore. Have included a picture of the horse (Lanagen) that I was riding, have also ridden him quite a few times.
