In one sentence, describe what the following article is about: Dermatitis is the most common type of skin inflammation, and is also known as a rash. Rashes are a swelling or irritation of the skin, and can be itchy, blistered, or bumpy. A lot of times, you can treat rashes at home, but if your rash appears frequently or lasts more than two days, it is time to consult your physician. If your rash is so uncomfortable that you are constantly distracted, contact your doctor right away.  Dermatitis is not contagious. When you call your doctor's office be sure to describe your symptoms in detail, especially any vomiting or fever. Be sure to mention if you have been exposed to a new environment, new foods or new products, such as soaps or lotions. If your doctor cannot see you within a day or so, you can try going to a walk-in clinic. Many pharmacies offer in store clinics. A doctor or nurse practitioner can examine your skin and help you figure out a treatment plan. If you have a chronic (recurring or persistent) case of skin inflammation, it is probably time to visit a dermatologist. A dermatologist is a doctor specializing in treatment of the skin. They can help you figure out the underlying cause of your skin issue and prescribe any necessary medication.  Ask your primary care physician to recommend a dermatologist that they trust. Make sure your insurance plan covers the dermatologist that you choose. There are many over-the-counter medications that can help heal your skin inflammation; however, it can be overwhelming to try to select the product that will be most beneficial to your individual problem. Your local pharmacist is a great resource. They are familiar with the active ingredients in many products, so ask for advice on which one to purchase.  Remember that a pharmacist is a medical professional. Don't be afraid to describe your rash in detail and describe your symptoms. You can also ask the pharmacist to recommend a generic alternative to some of the name brand products. You'll get the same health benefits and save some money.
Summary: Call your doctor. Consult a dermatologist. Talk to your pharmacist.

Replacing your vehicle's catalytic converter isn't quite like replacing a tire — you'll need to raise the entire vehicle off of the ground, rather than just one corner. It's very important to find a level spot to do this maintenance on your car. If your car is not stable, you risk serious injury or death if your jacks fail. If you have access to a professional-quality hydraulic lift and know how to safely use it, this is also an acceptable way to lift your car when replacing the catalytic converter. If your vehicle hasn't had an opportunity to cool down after running, its exhaust system can still be quite hot. To reduce the risk of painful burns, give your vehicle a chance to adequately cool down before working on it. Depending on your vehicle's exhaust system, this will usually be a matter of just a few minutes. To test the heat of the exhaust system, put on a pair of heavy mechanic's gloves and gently brush the exhaust tube with the back of your hand. If you can't feel any heat, you may cautiously repeat this test without the glove. Slide under the vehicle and locate the tubes of the exhaust system, which should run all the way to your vehicle's rear exhaust. The converter should not be terribly difficult to find — it will usually take the form of a rectangular or rounded "box" in the middle of your exhaust system. Some models can have a roughly cylindrical shape. Check to see whether the converter is bolted or welded to the rest of the exhaust system at its connection points. You may need to take it to an auto shop to have it repaired if it has already been replaced and welded back into position, rather than bolted. You can still replace a welded converter if you have access to a sawzall (or similar tool) and a welding machine and know how to safely use both, but these advanced tools are beyond the mastery of most amateur mechanics. Most modern catalytic converters are equipped with one or more oxygen sensors that monitor the efficiency of the car's exhaust system continuously. If your catalytic converter has an attached oxygen sensor, use an oxygen sensor socket and a ratchet wrench to disconnect it before proceeding. When you're done, move the sensor out of your way so that it doesn't interfere with the rest of the process. Catalytic converters that are bolted in can sometimes have bolts that are rusted, partially-corroded, or "jammed" into their nuts. These bolts can be very tricky to remove, so loosen them up by applying a penetrating oil (available from most auto stores). Allow the oil to seep into the bolts and lubricate them for several minutes before attempting to remove them. Use an appropriately-sized wrench to begin loosening all of the bolts before you start removing them. Once all of the bolts are loosened (but still attached), remove the "rear" bolts (those closest to the open end of the vehicle's exhaust) before removing the "front" ones (those further away). Remove the converter when you're done. You may have to support the exhaust once the converter is removed. If your converter is welded into the rest of the exhaust system, rather than bolted in, the only way to remove it is to physically cut it out of the pipes it's connected to. Most mechanics will use a sawzall or similar tool for this purpose. Cut along (or near) the existing weld lines, then remove the converter after it's cut free.  If you finish and the converter won't seem to budge, you may want to use a hammer to knock it out of its place as long as you take care not to damage or rattle any other parts of the exhaust system (this can lead to harmful exhaust leaks down the road).

One-sentence summary -- Park in a level place and jack the vehicle up at all four wheels and support on jack stands. Allow the vehicle's exhaust to cool down. Locate the catalytic converter. Remove the O2 (oxygen) sensor from the catalytic converter. If bolted, apply penetrating oil to the bolts. Remove the bolts at the back end first, then at the front. Alternatively, for welded-in converters, cut the converter out.

Problem: Article: Some of the chemical compounds in garlic help to counteract infections of the lymphatic system. Get 2-3 cloves of garlic and crush them. Spread this mixture on top of a piece of bread and eat it. Repeat this process daily and watch for the swelling to improve. Get a full glass of tap water and mix in 1 tablespoon (14.8 ml) of apple cider vinegar. Drink this mixture 2 times a day until you feel better. The acetic acid in the vinegar will help to rid your body of harmful bacteria that can abscess inside swollen nodes. If you are vitamin C deficient, then your body will not be able to fight off infection effectively. You can get additional vitamin C by taking a supplement or by eating the right foods, such as oranges and strawberries. If you decide to take a supplement, make sure to clear it with your doctor. Mix together 2-3 drops tea tree essential oil with 2-3 drops coconut oil. Use a cotton swab to apply this mixture on to the irritated nodes. Repeat this process a maximum of twice daily to avoid irritating your skin.
Summary:
Eat raw garlic cloves. Drink an apple cider vinegar and water mixture. Get enough vitamin C. Rub tea tree oil into the swollen skin.
