You can use steroids while suffering from candida but I would try to get the candida situation addressed first. It shouldn't' take too long. Most people can cure candida in a few weeks if they take the proper steps.
Candida is a yeast overgrowth and imbalance of gut flora in your digestive tract. Antibiotics, a diet high in refined sugar and birth control supplements can all lead to candida.
To stop the growth, you will need to eliminate all the refined sugar and processed carbohydrates from your diet. Be careful for hidden sugars in foods like yogurt and granola bars. To build up the friendly bacteria in your GI tract, increase your consumption of fermented foods like yogurt, kombucha, kefir, sauerkraut and kimchi.
