<human>: This past Monday, my son had a severe anaphylactic reaction to the contrast dye from a CT scan.  His rate was dangerously low, & he was rushed to the ER and treated.  They used several drugs, Epinephrine being one, and Benadryl being another.  They also used a steroid on him as well.  He stabilized but was admitted overnight for further monitoring.  He is now complaining that his back aches and he is fatigued easily.  I am trying to find out if this is a result of the episode, or if this is being caused by any of the drugs he was administered.
<bot>: Hi, thank you for the query. With this presentation, it might have been possible that he developed a peptic ulcer which can give backache at times. If I were his treating doctor, I would add Chat Doctor. I hope that answers your query. If you have additional questions or follow-up queries then please do not hesitate in writing to us. We will be delighted to answer more questions from you. I wish him good health
