I went to a sports doctor in 2003 because of my reoccurring back pain, they did a MRI on my back. After looking at the findings, before I said a word to the doctor he told me that I was a runner and in the military, he said in 3 years I will be begging for help. Three years to the day, I herniated a disk in my lower back and I could not walk. The doctor told me that I needed a discectomy of my disk (l4, L5), he also said I could try other options (chiropractor, acupuncture, etc.) or whatever I wanted to try but none of it would work. I did the surgery in in mid 2006, the doctor said to get out of the military, if not I would be walking with a cane when I did. I got out of the military and the doctor set me up with a set of exercises for me to do, change of lifestyle and diet, no more rucking with over 125lbs. Today I have no back pains and I am not on meds. I am back to running, rucking and shooting at 63 years old. The key is to find a good doctor that understands your lifestyle and for you understand your limitations. My doctor gave a five year plan from my diet to exercises and load limits. You don't have anything to prove to anyone, do what you need to do manage you back pain.
