Hello I am a 66 year old male..I hyperextended my low back lifting a 35 year old client into the bathtub 21/2 years ago..I have had surgery in the L-5 to L-1 areas 2 years ago. I still Have serious pain in the illium area about 4 inches off to the right of my spine around the beltline area.. The pain prevents sleeping. Upon standing after sitting for 10 minutes or so, the front of my right thigh goes numb and tingly.. also there is a burning sensation about 1/2 an inch under the skin at the same area. When standing straight up and leaning either to the right or left, it will generate a sharp pain in the same area...Also I get cramps in my calves, ankles, feet and toes 3-5 times a night, 8 being the most. this also prevents sleep.. I need to get up and walk them off.. I have also been diagnosed with a neurogenic bladder. Also both feet and ankles have swollen up several times. The pain in the illium area makes my right buttocks feel like a large bruise... Maybe I have torn muscles or ligaments in that area? What is the best diagnostic technique to examine the area?
