Article: Serious reactions to the flu vaccine are uncommon. However, you may still have an adverse reaction to the injection or nasal spray vaccine (The nasal flu vaccine is not currently recommended). Recognizing the common side effects of the flu vaccine can help you figure out the best way to treat them. Adverse reactions include:  Soreness, swelling, or redness at the injection site. Headache. Low grade fever (below 101 degrees Fahrenheit/ 38 Celsius). Nausea or vomiting. Muscle aches. Cough or sore throat.  Runny nose. Most side effects from the flu vaccine go away in two days. The most common adverse reactions happen at the injection site. These usually include redness, soreness, or slight swelling. Taking a pain reliever such as ibuprofen can ease any discomfort and decrease swelling.  Take an NSAID (non-steroidal anti-inflammatory drug) such as aspirin, ibuprofen or naproxen sodium. These can relieve pain and reduce swelling or inflammation. Follow dosing instructions as directed on the product packaging or by your doctor. You may have itching, soreness, or discomfort at the injection site. You may even experience some lightheadedness or weakness. Putting a cool compress either on the injection site or your face can relieve these adverse reactions to your flu vaccine.  Place a cool washcloth or ice pack on the injection site if you have any swelling, discomfort, or redness. Use as often as necessary for 20 minutes at a time until your symptoms go away. Put a cool, damp washcloth on your face or neck if you have any dizziness, lightheadedness, or sweating.  Remove the compress if your skin gets too cold or numb. The injection site may bleed a bit following your vaccination. In some cases, it may continue to bleed slightly for a couple of days after the injection. If this happens, put an adhesive compress over the site until it stops bleeding. Contact your doctor if the bleeding doesn’t stop within a day or two or gets worse. Some people may get dizzy or even faint with a flu shot. In general, these adverse reactions won’t last longer than a day or two. The best way to treat dizziness and prevent fainting is rest. Having a snack while you rest can boost your blood sugar and help you feel better.  Sit or even lie on the floor for a few minutes if you’re feeling dizzy. Loosening any clothing or sitting with your head between your knees may help the dizziness go away.  Eat a small snack to boost your blood sugar and help minimize any dizziness you may feel. Aim to eat a healthy snack such as a piece of string cheese, toast with peanut butter, or apple slices. Many people experience a low-grade fever (below 101 degrees Fahrenheit or 38 degrees Celsius) following the flu vaccine. This is a common reaction and usually goes away within one to two days. If the fever bothers you, taking ibuprofen or acetaminophen can help decrease the your temperature as well as any discomfort you may have from it such as muscle aches.  Follow packaging instructions or your doctor’s orders for treating your fever with ibuprofen or acetaminophen. Contact your doctor right away if your fever doesn’t go away after two days or increases above 101 degrees Fahrenheit or 38 degrees Celsius. Itching at the injection site is also a common adverse reaction to a flu vaccine. In most cases, this will also go away within a day or two. However, you might find the itchiness uncomfortable. You can use an antipruritic, or anti-itch, medication to relieve any itching sensations at the injection site.  Apply a hydrocortisone cream every four to six hours to relieve itching. If the itching is severe, your doctor may prescribe oral prednisone or methylprednisolone. Take an antihistamine such as diphenhydramine (Benadryl) or hydroxyzine (Atarax) every four to six hours to control injection site itching.

Don’t rely on a tip from a friend or neighbor.  The right brokerage service can make the difference between financial success and failure.  Before choosing an online brokerage, ask about details like pricing and the available investment choices.  Find out about the customer service they provide and whether or not they offer resources for education and research.  Finally, find out about their security practices. Depending on the amount of experience you have, you may require different levels of service from an online brokerage service.  Some services offer personal advice, which may be beneficial to beginners.  You may pay higher fees for these services, but if you’re just starting out, you may think the fees are worth it.  Online brokers that offer tools and advice to help beginner traders include E-Trade, ShareBuilder, Fidelity, Scottrade and TDAmeritrade. ShareBuilder also offers an ATM card that gives you access to uninvested funds. If you can do all of the research yourself and don’t need personal advice from a broker, then consider working with a discount online brokerage.  You can start with a smaller sum of money.  Also, you have access to more investment choices.  In addition to stocks, other investment choices may include options, mutual funds, exchange-traded funds, fixed income funds, bonds, certificates of deposit and retirement accounts.
