Article: The real trick to motivating yourself to exercise is to not think about it, and just throw yourself into it. Taking action and getting moving can stimulate a response in you emotionally and encourage you to keep at it. You might be dreading going for a run or lifting some weights, but generally once you’re going your feelings will change.  Exercise allows more oxygen into your brain, which in turn releases more chemicals that make you feel good. Once you’re exercising you will have more positive feelings, and your mood will improve.  This is why exercise is a great natural anti-depressant, and is often recommended for people suffering from mild depression. One of the most important factors in maintaining your motivation is finding something that you actually enjoy doing. Exercise shouldn’t be a chore that you have to force yourself to do. It might start out like that, but finding forms of exercise that you like will make a huge difference in getting motivated. Keep an open mind and try new things.  Don’t be put off by the memory of freezing cold cross-country runs when you were at school — there’s more to exercise than this. You could do anything from a ballroom dancing class, to badminton, horse riding, or martial arts. When you find something fun, keep it in your routine, but still look for some variety. This won’t be possible for everyone, but if you live within running or cycling distance to where you work, turn your commute into part of your exercise routine. Often people struggle to put time aside to exercise, but by exercising on your way to and from work you are being active without having to set aside any extra time.  Running or cycling to and from work will also help you clear your mind in preparation for, or to recover from, a stressful day in the office. Cycling to work is a great workout and will help you get into the habit of cycling and exercising more generally. If you are busy it can be tough to find time to exercise, but you are more likely to stick to it if you firmly book it into your schedule. Go through your diary carefully and try to carve out a regular window that is free most weeks, if not every week. If you do exercise at the same time and on the same days every week, you have a better chance of maintaining it.  Sooner or later the exercise will become as deeply embedded in your schedule as everything else. You’ll even find yourself looking forward to it as a break from the everyday grind.  Habits and routines take a while to form, but they can be very powerful once they are in place. A good way to get more exercise in your day is just to add in little bits of physical activity whenever you can. Making small changes can add up to a big change in the long-term, as well as helping you change your outlook and get more used to being physically active. Some examples of small changes you can make include:  Taking the stairs instead of using the elevator Walking or cycling to the shops instead of driving Taking a brisk walk when you have a break at work Put yourself in a position where you have to walk and don't think about it being a form of exercise. This could be done by getting off the bus a few stops earlier to home or work, or by walking anywhere you can in a reasonable distance such as to the grocery store, school, the post office, or a friend's house.  For example, you could park further from stores so that you have further to walk to start shopping. The more often you do this the easier it will become as you get used to it.

Article: Here's the knowledge you should be armed with:  Non-steroidal Anti-inflammatory Drugs (NSAIDs) are prescribed for relieving pain and reducing inflammation (redness, swelling, pain). Well-known NSAIDs in the pharmacies are  Ibuprofen and Diclofenac salts (“Voltaren or Cataflam”); most are available in variable dosage forms. Tablets should be taken when needed (when having pain) but a usual dose of Voltaren 50 mg twice daily after meals should be enough.  Osteoporosis drugs such as Alendronate (“Fosamax”) helps in slowing the progression of AVN.  Cholesterol drugs are used to decrease the fat concentration in the blood circulation caused by the intake of corticosteroids; this prevents blood vessel blockage that leads to AVN. Blood thinners such as Warfarin help patients with clotting disorders to prevent clot formation that can block the blood vessels. This is a process that stimulates the body to grow new bones to replace the damaged area. It’s performed during surgery by being applied around the bones as electromagnetic fields, putting electricity directly to the bones or by attaching electrodes to your skin. It's not surgery per se, but it is generally used in conjunction with surgery. If surgery puts your bones in line, electrical stimulation sets the ball in motion. However, it's not right for everyone, so ask your doctor if it's a feasible option. More than 50% of patients with AVN will need a surgical treatment in about 3 years of diagnosis. Your doctor will determine which type of surgical therapy you may need. Here are the details:   Core decompression. The surgeon removes parts of the bone's inner layer. The aim of this is to decrease the pressure inside, increase the blood flow, and let the extra space stimulate new healthy bone tissue production with new blood vessels.  Bone transplant (graft). This is a transplantation process of a healthy bone section from another site of your body to support the affected area, usually done after a core decompression. Increasing the blood supply may be done by performing a vascular graft, including both an artery and a vein.  Bone reshaping (osteotomy). This is where the surgeon removes a section of the affected bone above or below a weight bearing joint to change its shape in order to decrease the stress on it. This is effective for early stages/small areas and postpones the joint replacement.  Joint replacement. In late stages, when totally collapsed or damaged and with medication failure, the damaged joint is replaced with an artificial one, usually made from plastic or metal parts. After surgery, it is absolutely imperative that your bones: A) heal, and B) heal correctly. Physical therapy (done regularly) will ensure that both of these things happen. Here's how it's beneficial:  Your physical therapist will hook you up with crutches, a walker, or some device to reduce the weight the joint has to bear. This will greatly speed up the healing process. Your physical therapist will work on exercises with you to prevent joint deformity and improve your joint flexibility and mobility. Very important things!
