I think I may have a kidney stone but I'm not sure. I fell on Friday and the back pain began on Saturday night. I took Aleve on Sunday night. It was better yesterday and last night so I took nothing. Now it's back. I took Aleve at 6pm and again at 7:30pm according to bottle directions. This time it isn't helping much. I've been using Icy Hot on my back thinking it is muscular from the fall. It isn't helping. I just took my temp and it was 100.1. I donated blood yesterday and when they took my temp it was 99.9. We are in a heat wave in my area so I thought it was that. Now I'm not so sure. Help?
