INPUT ARTICLE: Article: If the wound completely punctures through the skin or is wider than two millimeters, you should consult a doctor or visit an emergency clinic. If you have trouble closing the wound on your own or can see any exposed muscle or fat, you will likely need stitches. Getting stitches within a few hours of the injury will reduce the risk of scarring and infection. Keep in mind that wounds with jagged edges are more likely to become infected, so make sure you see a doctor if you have this type of wound. Call a doctor immediately if redness and swelling spread beyond the wound or infected site. If you've already seen your doctor, call them for a follow-up if a fever persists for two days after starting an antibiotic, or if the infected wound shows no signs of improvement for three days after starting an antibiotic. Signs of a worsening infection may include: Increased swelling Red streaks traveling away from the wound A foul odor coming from the wound Increased amounts of pus and fluid coming from the wound Fever Chills Nausea and/or vomiting Swollen lymph nodes When you have your doctor examine the infected wound, discuss whether you should take topical or oral antibiotics. A topic antibiotic is an ointment that you apply directly on the infected area and is the most common form of treatment. Oral antibiotics, or systemic antibiotics, are taken by the mouth and are best if your doctor believes the infection is spreading or if your immune system is compromised. Tell your doctor about fever or any other symptoms, and be sure to mention any chronic health conditions or medications that might have weakened your immune system. It's always best to talk to a doctor about getting a tetanus shot if the wound is deep or dirty. Puncture wounds from soiled or rusty surfaces can cause tetanus, but most standard vaccination programs protect against the disease. If you haven't had a tetanus shot in the last five years, you might need a booster. You should contact your doctor immediately if you have any concerns about the nature of your injury or about your existing medical conditions. For example, be sure to consult a doctor if you take a prescription blood thinner or if your immune system is compromised. In addition to wounds from rusty or soiled objects, it's best to see a doctor for wounds from animal or human bites or with hard to remove debris. Also, keep in mind that some people are at an increased risk of infection, such people who are diabetic, elderly, obese, or immunocompromised (those who have HIV/AIDS, are undergoing chemotherapy, or who are on a steroid medication). In some situations, you may need to seek immediate medical care. Symptoms that indicate a need for immediate care include: Feeling short of breath Having a rapid heartbeat Feeling confused Having excessive bleeding that soaks through your bandages Feeling like your wound is ripping or noticing that it has actually come apart Having severe pain Noticing red streaks coming from the infected area

SUMMARY: Have deeper wounds sutured. Make an appointment if the infection worsens. Discuss topical or oral antibiotics with your doctor. Ask your doctor about getting a tetanus shot. Consult a doctor about chronic conditions and other concerns. Seek immediate medical care for severe symptoms.

In one sentence, describe what the following article is about: Activated carbon is a special filter media that removes chlorine, chloramines, and organic compounds from water. Some activated carbon filters can be connected to your home's water supply, or you can buy a filtered pitcher that uses an activated carbon filter. Activated carbon filters remove both chlorine and chloramine. Choose an activated carbon filter that has been certified by NSF International, a nonprofit that tests and certifies water filtration products. Reverse osmosis refers to the process in which ions and particles are removed from the water. Reverse osmosis systems can be installed directly beneath your kitchen sink or where your water supply enters your home, and are therefore very convenient relative to other dechlorination methods. But they're also very expensive, often reaching several thousand U.S. dollars. Additionally, reverse osmosis filters are energy-intensive and produce large volumes of wastewater. All filters need to be changed eventually. The amount of time that passes between filter changes depends on your filter's size and how heavily it's been used. Check the manufacturer's directions to ensure you're changing your filter with the appropriate frequency. Boiling creates heat and aeration (via bubbles), the combination of which is sufficient to remove volatile chlorine after 20 minutes. If you're trying to dechlorinate large batches of water, however, this method is probably not practical. Boiling for at least 20 minutes will also remove chloramine, which is added instead of chlorine in some areas.
Summary: Use an activated carbon filter for drinking water. Install a reverse osmosis filter in your home. Change your filter as needed. Boil chlorinated water for 20 minutes.

INPUT ARTICLE: Article: Stand with your legs shoulder-width apart. Keeping your legs straight, reach for your right foot. Hold this position for ten seconds. Then reach for your left foot and hold this position for ten seconds. Finally, reach toward the center and hold this position for ten seconds. Sit in a chair with your knees bent. Place your hands on the sides of the seat. Straighten the leg with the affected knee until your heel is resting on the floor. Keeping your leg straight, gradually lift it off of the ground. Lift your leg as high as you can. Then gradually bring your leg back down to the resting position. Practice one set of five to ten repetitions, four to five times per week. Place a mat on the floor. Lie on your stomach with your legs straight. Bend your arms and place them underneath your chest. Slowly bend the affected knee. Bend your knee as far as you can. Then slowly bring your leg back down to a straight position. Do three sets of five to ten repetitions. Practice this four to five times per week. Stand in front of a chair. Place your foot with the affected knee on the seat of the chair. Keep your standing leg straight. Move the foot of the standing leg back until your knee is bent at a 95 to 100 degree angle. Gradually lean forward. As you lean forward push into your knee. Then gently push back to the starting position. Do a set of five to ten repetitions. Practice this four to five times per week.

SUMMARY:
Stretch your legs. Try a sitting knee straightening exercise. Do an active knee bend. Try a step up lunge.
