Back end? I have three words for you. Milk of Magnesia. That stuff works fast (within an hour) and isn't as harsh as some other products. Make sure that you take in lots of fibre on a regular basis.
Front end? Here's where things get tricky. There could be a real medical issue behind this. You could have bladder crystals (or kidney stones), or if you're a guy you could have a prostate issue. Either way, you should be getting checked out by a doctor. At the very least they can pass a catheter into you and get you some relief. [ NinjaNeer's advice column | Ask NinjaNeer A Question ]
