I wear a radio on my waistband, over my belt, at work. I wear it in the area of my left posterior iliac crest. The other day I bent over to pick something up and felt a sharp zinging pain over my left iliac crest that shot across my back towards my right iliac crest. Now I have a constant pain over the area of my left iliac crest. it doesn t radiate anywhere else. It s almost intolerable while lying down or sitting. It s still there when I m standing but much less severe. It also feels better when I arch my torso (my back curved inward, abdomen pushed out in front of my body). Any thoughts on what I might have injured and/or suggestion on what I should do to improve how I feel?
I understood your problem. It may be ligament /muscular catch in lower back. For 3to 4 days you have to apply ice/ice packs over the painful area. If pain will not subside than you have to consult physiotherapist. Many pain modalities and some exercises will teach you.
