I was wondering if anyone could tell me how I would know if the steroids were helping or not. My son is 3 1/2 years old and has been on Deflazacort for about 4 months now. We haven't noticed any improvements in strength or stamina. He has recently started tip toe walking on occasion and there have been a couple of times when he would limp or drag a leg for a period of 3-4 days. I thought that we would see improvements in the first couple of months, but it seems that all we are seeing is new symptoms. I think that I read somewhere that steroids don't help everyone, but I am not sure about how that is decided.
