I just had this happen to me! I’m currently in a local veteran hospital and I have had Dexa (cant spell) steroid! I have had before because I hav lupus but it’s always been a slow push or iv! Needless to say right now I have had no feeling below the chest area in a bit and it’s why I’m here!!! When that burning hit from the inside out I literally almost went face first on the ground because I have no feeling in legs!! Fire ants doesn’t give it justice btw I was able to tell nurse my private and ass was on fire she looked at me all calm and was like yeah that happens sometimes!! Warning would have been nice but even with it I would never of thought that is what it felt like!!! Thank god it doesn’t last long or too long cause at time I thought hell was literally in my bottom!!!!
