I can certainly "feel your pain" as I have been fighting chronic pain for eight years. This was due to a ski fall on my lower back and buttocks. Can you pinpoint any event or specific time that your pain developed? I hobbled around for the better part of a year before I found a private practice neurologist who put me on a cocktail of drugs the made my pain drop from about a seven down to about a two. I ws able to get back on my bike and start cycling 30-40 miles per week. Another thing that helped me was the implant of a spinal cord stimultator that helped stabilize my pain. I hope you've had an MRI to see if there is something that might be contributing to your pain.
I will say a prayer for you. No one really understands severe, chronic pain until it hits them. I wish for you better days ahead. May God grant you the strength and grace to get through each day.
