Problem: Article: If you believe you are experiencing an allergic reaction to antibiotics, seek medical help immediately, no matter how severe your symptoms are. Many allergic reactions are confined to skin rashes and will not result in any complications, but it's important to talk to your doctor about any reaction. Some rashes can be caused by Stevens-Johnson syndrome, a severe complication that needs hospitalization. Other rashes are a precursor to anaphylaxis, which can be life-threatening if not treated. Seek immediate medical assistance if you experience:  Fever Sore throat/mouth, with or without a cough Facial swelling Tongue swelling Skin pain Rashes and/or blisters Hives Difficulty breathing or tightness in the throat An abnormally hoarse voice Hives or swelling Nausea or vomiting Abdominal pain Dizziness or fainting Rapid heartbeat Feelings of doom If you're experiencing any allergic reactions to an antibiotic, you must discontinue using that medication, and avoid all exposure to it. Exposure can happen accidentally, so it's important to take preventative action.  Tell healthcare workers about your allergy any time you are receiving medical treatment of any kind. Ensure that this is included in your medical records for future reference, but don't ever assume medical personnel have seen the chart or know of your allergy. It is your responsibility to communicate your allergies when being treated. Wear a medical alert bracelet. These bracelets can be invaluable, especially if you ever require emergency care while unconscious. It alerts healthcare workers about your allergy in times when you cannot communicate your allergy.  You may want to carry an epinephrine auto-injector (commonly called an "Epipen"). This is typically only needed for people susceptible to anaphylaxis, but your doctor may recommend that you have one if your allergies are severe. In most cases, if you have a known allergy, your doctor will prescribe an alternative drug. In some very isolated cases where benefit outweighs the risk, and there are no alternative treatments, that may not be an option. If you must take a particular drug and have a known allergy to that medication, your doctor may work with you through a drug desensitization treatment.  During drug desensitization treatments, your doctor will administer a minimal dose of the drug you're allergic to and will monitor your symptoms. Then they will administer an increasingly larger dose every 15 to 30 minutes, over the course of several hours or even days.  If you can tolerate the desired dosage without any adverse reactions, your doctor may then safely prescribe a regular course of the medication.  This is usually done in severe cases and should only be done by a professional with training in emergency treatment.
Summary: Go to the emergency room or call emergency services. Stop taking the medicine. Ask your doctor about desensitization.

INPUT ARTICLE: Article: You can either buy a tachometer new, which usually run somewhere between $30 and $50, or salvage on old one for relatively cheap and install it into your car. The only other specialty item you'll need to complete the job is a package of quick-splice connectors, which are usually only a few dollars at the auto part store. The wires are about 16-18 gauge usually, so get connectors of the appropriate size. New tachometers may be set to work on 4-, 6- or 8- cylinder engines by removing the back cap of the tachometer to reveal the cylinder setting switches inside.  Set the cylinder switches to match the number of cylinders in your engine. Replace the end cap of the tachometer carefully to avoid pinching any of the internal tachometer wires. Use a screwdriver to refasten the end cap if necessary. Generally, there will be two switches--a 1 and a 2. Most of the time, both switches should be down for a 4 cylinder engine, while both should be up for an 8 cylinder. In a 6 cylinder engine, most of the time the 2 switch should be up and the 1 should be down. If you get a new tachometer, read the instructions to be sure. Depending on your engine, there may be a constant-flow wire and a pulse wire to the tach, as well as the additional wires for the ignition, lights, and other components. It's important to make sure you've got the correct wire for the tachometer, which means you might need to use a multimeter with a tach setting to test the wires correctly, and consult the shop manual for your engine. It's also important to note that some new tachometers are incompatible with solid-core spark plug wires and can be dangerous to connect without following the proper installation instructions for the tach. Before you mount it in the steering column, it's a good idea to hook up the wiring and and test it out while you rev the engine, to make sure it works. You don't want to go drilling holes in your steering column before you're sure you've got the wiring figured out. After you hook it up to the proper wires from the distributor and ground it correctly, it should give you an accurate reading of your RPMs as you rev the engine.  Ground the tachometer. Attach the tachometer ground wire to an engine ground of the car. This need not be directly on the battery. Much of the car frame is grounded to the battery by sturdy wires. Trace those wires to find a suitable attachment point.  Attach the tachometer pickup wire. The tachometer wire must be fed through a grommet in the passenger compartment to reach the engine compartment. This attachment point will vary from engine to engine.

SUMMARY: Get a tachometer and splicing connectors. Adjust the tachometer for the number of cylinders in your engine. Locate the output wire from your distributor. Test the connection.

In one sentence, describe what the following article is about: Place a cloth underneath the bat so the bottom does not get damaged. Use a table clamp to secure the bat so you can strike it easily with a mallet. Slowly test how much power you need to use so you don’t damage your bat. Swing the mallet with enough power to leave an indentation in the middle of the hitting area. If it’s difficult to see an indentation on the bat, loosen the clamp and hold it up to a light to see if you’ve made a dent. Repeatedly hit the entire flat area of the bat since a ball may be hit anywhere on the surface. Use the same amount of power you used to make your initial indentation across the face of the bat. The entire process should take about 6 hours. As you increase power, continue making the surface of the bat even so it is flat.  Split your time knocking the wood into 10 or 15 10-minute sessions so you don’t get burnt out.  Test the wood with your fingernail occasionally. At first, your fingernail should leave an impression in the wood’s surface, but after you’ve knocked it in, it will be harder to press. Ask a friend to toss gentle pitches to you with an old cricket ball so you can hit them back with the bat. This helps you detect if any sections of the bat hit unevenly. If they do hit unevenly, go back and strike the areas with a mallet again.  Using a new ball could damage the bat if it is hit improperly. Alternatively, put the ball in a sock and tie it to a rope. Put the rope over a tree branch to make a swing. Hit the ball as it swings back and forth.
Summary:
Clamp your bat down so the flat edge faces up. Hit the middle of the flat area so it dents. Strike the flat face of the bat until the surface is even. Repeat the process with harder hits until you’ve struck it 20,000 times. Practice hitting soft pitches with the bat.
