Does anybody notice that the longer you work standing causes your pain level to increase. I work 12 hr. shifts and feel good the first half of my shift then things start to hurt. When walking I'm fine but if standing in one place very long I start to hurt alot. Had another ESI yesterday and hope it helps but I just haven't been getting any long term relief from the shots. Just wondering what others do for this at their jobs. Injection was at my L3-L4 disc which is bulging on both sides and also shows DDD.
