I've had lower back surgery and have dealt with discomfort of some degree for about 20 yrs. I'll spare you all the details and cut to the chase of what works for me. I find a step, table, workbench or whatever that is the same height as my hip. Prop the foot on the bench and keep the back straight, and wait for the discomfort to ease. Then reach down and do your best to get your fingertips to your toe and pull it back toward you. Leg and back straight is important and hold that, leaning forward as much as possible while keeping the back straight, hold that for a count of 100. Stretching ligaments takes time and doing it for short periods doesn't accomplish anything but causing you pain. This stretches everything from the back of the knee to just below the ribs, and is where the majority of my pain begins. 13 months with the first injury and 27 with the second I have been through more physical therapy than anyone should have to endure. Once I figured out how to do this and keep it up regularly I don't have to go to the chiro but now and then, 3 times in the last 5 yrs, and my painkillers are gone but for the ibuprofen when I overdo things. Realizing what you can't do on your own and when to say I can't do that was the hardest thing for me. Do the stretch once in the morning and again in the evening for 2 or 3 days and you will feel a small twinge as things drift back into place and the discomfort will ease. Depending how long mine has been out or how much I overdid things it might take a few days to finally go away. The wallet and feeling better and getting overconfident is usually my undoing. I generally feel OK but have my limits with many days and sometimes weeks going by in relative comfort. I hope this works for you as well as it does for me, and please let us know how you're doing with it. I'm interested if no one else is. And have a good new year.
