Pulled muscle or stuck kidney stone? - stones stuck in ureter

Help! During the last week, I had moderate to severe pain in my lower back, but it is intermittent. I thought it was just a muscle strain, but I swear, I've got a nothing that I had! Now I think I can be a kidney stone stuck in my urethra? I had before the pain is usually sudden and intense that it took so long to torture.
Even better, to be completely gone for 1 days and spent the sand, but have now returned and is even worse!
