It may not work all the time. Depends on the person.
If you think on it, "What is writer's block?" and continue from there. For me, my mind literally goes blank. I try to write what comes later and that doesn't work either. Here are some of my tips.
1. Changing to another story? -Sometimes can help.
2. Going outside for inspiration? Even if it rains! -Walking around the place can get you somewhere to.
3. Just talking with some one else online or in the real world around you.
4. Spinning in your chair till your dizzy. -lol
5. Exercise! You may be bored?
6. Read or do something you have been wanting to do for the longest time!
7. Go to an old museum? -Maybe you can get a vibe. -shrugs-
8. Look at other languages and what their words mean. Even the different types of cultures.
For instance; In some places yes means no and no means yes. In Germany it is considered rude and in some places you are not allowed to have your hands in your lap during a meal or out at a diner. You have to put your hands on the table in front of you. Where everyone can see them! Because, they may think you are fondling one of the ladies or men.
And in some tribes, depending on what hand of yours is the dominant, you are not allowed to shake their hand in the normal English way of greeting. Because, out there they don't have soap. (I'll give you a hint. The living/bathroom conditions. Like a male using his main hand to hold his... You get the point. ^-^) It is considered an insult.
9. You can look at your story or stories you have written and read them from the beginning! Who knows? Maybe you can get inspiration or re-feel that joy, severe want that draws you in like a moth to a flame that started writing in the first place, to write again and continue where you had left off.
10. Read a ton of jokes or listen to some humor! 
11. Go with a friend or family member to anywhere in your town/city/village ect... -Some form of change is refreshing ne? Well, unless you have a phobia or are afraid of change.
12. My personal favorite. ^-^ Take a nap. Helps especially if you haven't had much sleep.
