Hello, My grandson Levi was diagnosed in March 2015 at age 2 and a half , as far as we know, the youngest person to have this terrible disease. He also had a fasciotomy at that time. He started having IVIG every month for about a year and then went to every 2 months and now is receiving a treatment every 3 months ( 2 so far ) . So far so good with no headaches or joint pain, so we are unaware of typical or specific symptoms from reducing treatments that dramatically and since he is not completely off not sure how much this helps except for others to know there is a very young patient who is/has drastically reduced treatments with no real side effects or withdrawals. Not sure if we will be able to completely stop but the trend is encouraging that that may be possible in the future.
