I am a 58 year old male generally very healthy.- swim and golf in the summer. 4 weeks ago I was smashing ice from my driveway (here in Canada) and I was forcefully scraping it. My arms were vibrating due to this forcefull activity. At some point I felt a massive shock in my back followed by overwhelming massive pain that literally froze me .Somehow I crawled to the house where my wife immediately got me onto the floor , gave ith mass does of Advil and a cold pack.. Had a locked highly sensitive lower back for next 7 days, and for the last 3 weeks suffering from overwhelming Siatica - mass pain in left buttocks is incredible, plus tingling left foot and outer calf which gives way to mass pain in left calf. Can stand or walk for about 1 minute. I get about a 1 minute of relief by sitting or leaning forward at a 45 degree angle. Again sitting and lying down are fine but immediately on getting up I have about a minute. I can walk on my heels and my toes no problem. Also can lie down and bring my leg to 45 degrees with no pain in leg and only a little in lower back. Have not worked for entire 4 weeks which is soon going to be a problem. Cannot walk any further thant the end of a short snow and ice packed driveway. Doss this a herniated disc ? I did go to physio and they gave me all these exercises to arch my back. Did not work. Odly the relief (which is only for a minute) is leaning forward. (Flexion bias). I can push a chair on the hardwood floor at 45 degrees (almost like a walker and that helps some) but is no way to live. Taking Tramadol and Celebrex waiting for an MRI which up here could be some time. Sorry for running on but the painn nd uncertainty are causing high anxiety. Any insight, suggestion feedback, diagnosis or prognosis would be most appreciated. Thank you for your time.
