Ouchh! Painful Lower Spine

I have back isssue's myself.My L-3/4 & 6 are arthritic/buldging and I have it in my right hip. Before I went to Ortho and found out exactly what it was. I was riding QH's and a 2 hr ride would kill me. I have since gone gaited and now I can ride 6 hrs. Of course I have had injections in my hip and I take daily meds for the back. But the jarring was hurting me and I can't quit riding so changing my riding style even though I miss my QH's keep me in the saddle...Another good thing is if you do stretching excercises for your lower back it will help out tremendously....As far as saddles. I had a big Horn gaited saddle, very comfy but didn't fit the horse. I now ride in an Eli Miller Buena Vista and I go Mnt riding 4-6 hrs a day and I'm alot sore like I was riding in my CY.... Good Luck.....
