If the pain keeps up or you have any burning sensation when you do go, it might be a urinary track infection. I don't know what type of job you have, but I would try and speak with someone about going when you have the urge, as holding it is not good. I'm sure it is not anything serious, or you would be in real pain, but trying to hold it too long constantly might cause problems down the road for you. Good luck!
