Problem: Article: If you are experiencing extreme knee pain, swelling, limited mobility, discoloration, or other symptoms that interfere with your daily life, you should see a doctor. You should also see a doctor if you know you have injured your knee, like in a sports contact accident or a fall. Getting the correct diagnosis can help treat your pain and heal it. Other reasons to see a doctor include exquisite tenderness, inability to bear weight, a cold extremity, or numbness/tinging. If you don't get the cause of the pain accurately diagnosed, you will only be treating the symptom and not the cause, so it will not heal. When you go to the doctor, you should be as specific with your symptoms as possible. Saying that you have swelling and pain refers to just about every knee problem you could have. Try to give your doctor information about any activities you were doing before the pain started and any other symptoms. Let your doctor know if your knee is locking or making popping noises. Tell the doctor if the kneecap was dislocated but moved back. Include any changes in color or size. Tell your doctor where on your knee the pain is. The location of the pain can help them come to a diagnosis. Is it inside or outside of your knee? Is it in the center, in the front, or the back? Does it hurt just above or below the knee? Tell your doctor about any sudden movements that caused knee pain, if you were doing a physical activity recently, or if you have fallen. Another way you can help your doctor is by describing your pain. This may take some consideration on your part. Do you consider the pain constant or only when you do certain things? Is the pain a dull ache or a sharp severe pain? Try to be specific because different types of pain can help your doctor narrow the cause. Tell your doctor when you feel the most pain. Tell your doctor if only certain activities cause the pain, or if it starts but gets better when you move certain ways. Let your doctor know if you have done the RICE method - rest, ice, compression, elevation - and how that affected the pain.
Summary: Visit your doctor. Detail your symptoms. Describe your pain.

In one sentence, describe what the following article is about: For your redstone torch to flicker, it must be mounted on a wall, rather than planted on the floor. Find the spot where you want your final flickering torch to be. Note that the torch must be mounted on the highest block of the wall - for the "flicker" to work, it can't be any lower. Also note that because it's necessary to lay redstone dust on top of the block the torch is on, you'll want unimpeded access to the top of the wall. Equip your redstone torch and mount it on the top block of the wall. To be clear, you must mount it on the side of the top block in the wall, not on the very top of the wall. Lay one redstone dust on top of the block with the redstone torch on it. This should cause your torch (and the dust) to begin to flash on and off. If the redstone dust on top of your wall ruins the aesthetic of your structure, you may want to hide the dust by concealing in the construction of your wall. Use any sort of block you wish to conceal the redstone dust. Note, however, that, if you're creating a building, you may need to work these blocks into the plans for your ceiling..
Summary: Find a suitable wall. Place your torch at the top of the wall. Add redstone dust to the top of the wall. If desired, surround the redstone dust with blocks.

In one sentence, describe what the following article is about: Giving Christmas presents is a tradition this time of year. Kids usually get toys from "Santa" on Christmas Day, but it's also customary to give gifts to others you love. Presents don't have to be big or expensive. Even giving a chocolate bar, baked goods, or small handmade gifts is welcome. It's also a good time of year to offer gifts to those in need. For instance, you can give toys to toy drives for families who are down on their luck or send packages to troops overseas. For a bit of fun, try opening 1 gift on Christmas Eve. Books or pajamas make good Christmas Eve gifts. However, while gift-giving is fun, there's no reason to go into debt for it. Make sure you spend only what you can afford. Sending Christmas cards is a tradition this time of year, and it's a way to let people know you care. Include a little note about how you're thinking of the person and wish them well. You can also send Christmas cards to nursing homes or troops overseas to let them know they're remembered at Christmas. Charity is a hallmark of Christmas, and one way you can participate in that is to pick a charity to give money to. Some common ones that people give to this time of year include food banks, homeless shelters, and other charities that serve those who are down on their luck. You won't have to look hard to find someplace to give, as many charities put up donation centers and boxes this time of year. You could also buy groceries anonymously for a family you know is struggling. You don't have to give money to help out this time of year. Offer to hang Christmas decorations for a neighbor who can't do it or send them baked goods. Collect food, blankets, coats, or other supplies for local charities, or volunteer at a homeless shelter or soup kitchen on Christmas Day. If you want to keep Christmas going throughout the year, try volunteering your time once a week!
Summary:
Give presents to friends, family, and people in need. Mail cards to friends, family, and those in need. Donate to your favorite charity. Give your time to charity and neighbors to spread Christmas cheer.
