I know there are some in here that seem to have this problem...lol. I sprain mine at least one good one once just about every year so it seems. Last year I did it so bad I had to go to the emergency room because I could hardly walk. He gave me a two shots in the lower back and it helped but I was still out for about a week. Friday I was kneeling down and installing a control board and BAM, I must have turned a certain way and sprained it again.I play hell in the morning getting out of bed and doing something simple like walking down the stairs gives me a fit. I will be making a appointment with my primary care physician to see it he can give me the same shot the doc gave me last year. What have you guys be doing for this kinda of pain.
