Legged horse symptoms and conditions

My son (9) was on advair off and on for a while for severe asthma. I noticed depression, anxiety, fatigue and fibromyalgia type pains all over his body. I had him checked for lupus and other diseases and all negative. He also developed a severe rash between his legs causing much pain and discomfort as he had to walk like a bull-legged horse-riding cowboy. Showering often never helped. I assume he has candidis yeast infection(systemic). He was finally put on Prozac and I took him off Advair against my doctors advice. i took him off slowly and your body may need to make it's own steriods and not go into shock. He takes as much albuterol as needed to get him better and then i give him prednisone for 3 days when things become an emergency. tTe prednisone leads my son to anger and suicide but it goes away after he finishes his course, but it saves his life. He is now 13 and much happier and his face and body has thinned out by half. I will never give my son Advair again.
