Infections are really not caused by Enbrel, or even germs. They are caused by not supporting the immune system. Do you take zinc? Vitamin A? Vitamin D? I take handfuls of vitamins and minerals (no herbs), and I never get sick. Before I did that, even before I got RA, I was sick constantly - pneumonia and bronchitis, which developed into asthma. It cost money to buy all these vitamins, but do some research. Even my 80 year old mother has noticed what a difference zinc esp. can make. Don't know what the mechanism is, just that our food is depleted, and our bodies are compromised, so you really need the supplements.
Regardless of how little pain you are in - you need med support if you are diagnosed. This disease always progresses, whether you feel it or not. My cousin had RA for 55 years (since age 1). She was only taking prednisone, and is very deformed. Two years ago, she had an RA flare in her throat, almost died from hypoxia (lack of oxygen) from a heart attack, and now has a permanent trach - a hole in her throat for breathing. I suggested she get on at least methotrexate, and the swelling went down, and she was able to get out of the hospital, at least.
Enbrel didn't work for me - headaches. I am on Kineret, and it has been great. It clears through the kidneys, no infection worries, but a daily shot. There are many biologics - Remember flares mean damage. You want to slow that to a minimum, because over your life, you will become severely disabled. Slow and steady deterioration is as bad as hard, fast flares. Side effects from drugs are not as big an issue. Even if the drug stops working, you can always switch to another. As someone else said, there is no cure - you have to take care of yourself.
This is a really stupid post. Of course it is important to take vitamins and eat healthy. But you clearly do not have children or are not around small children. I was never sick before my son started bringing home things. And of course Enbrel is the main culprit...it lowers your immune system.
