Hello, I understand your problem. I would have healed you better if you would have mentioned about your condition without mentioning about your condition you are only mentioning about the stperiods and for this I could only say that steroids are safe untill the doctors prescribe you and you following them. Steroids are the substance that which are given only in selective conditions to regularity immunity or in inflammatory conditions. They have sideeffects like immuno suppression and increase in blood sugar levels etc. Inorder to know more about them kindly follow up with your doctor you have prescribed you actually. Thank you.
