Solu-Medrol and allergic reaction

I was given solu-medrol for an allergic reaction to something unknown. I was given benadryl just prior because of my itching hives.
Immediately after the RN injected the solu-medrol into my IV I started choking, I couldn't catch my breath, I felt as if I had a rush of adrenaline but at the same time it felt like my heart was fluttering. My blood pressure and my heart rate jumped up considerably. I was unable to speak and had a hard time swallowing. My vision was effected and I had light sensitivity, everything suddenly seemed very bright. My thought process was very distracted, I would try to speak and within a second forget what I wanted to say. I had to concentrate extremely hard just to get out a single word.
I also had slight numbness or loss of sensation in my hands.
I don't want to know what would have happened if I hadn't been given the benadryl first! I felt as if someone was inducing brain damage onto me and instantly turning me into a vegetable.

I TOO HAVE HAD SIDE AFFECTS,BUT LIKE EXSPLAINED ALREADY,I AM GLAD THERE IS THIS DRUG,I HAVE BEEN DIAGNOSED 2.5 YRS AGO WITH CIDP AND I TAKE IVIV INFUSION EVERY MONTH, I USE THE SOLUMEDROL FOR PROTECTION AGAINST THE SIDE AFFECTS OF THE IVIG,( I HAVE HAS ASSEPTIC MENNINGITIS 2 X PRIPOR TO THEM STARTING ME ON THE SOLUMEDROL
I AM ALSO ON BENADRYL FOR ALLERGIC REACTION DURING TREAT WHICH DRIP HAS TO BE AT A VERY LOW RATE STARTS AT 50 DRIPS AND THEY EVENTUALY GET THE IVIG UP TO 125 ,TAKES 5 HRS ,I CANT HAVE IT ANY FASTER ,TO MANY ADVERSE SIDE AFFECTS
LATELY I AM ANXIOUS RESTLESS IRRATABLE, HUNGRY AS ALL GET OUT THE FIRST 4 DAYS AFTER TREATMENT I HAVE GAINED 50 LBS I AM DEPRESSED,AND SO WORRIED ABOUT THE HEPERIN RECALL AS WELL ,THEY USE IT DURING MY TREATMENTS TO PREVENT BLOOD CLOTS
SO IS IT LL WORTH IT ,,WELL WHEN I AM SICK I WOULD SAY NO,,BUT I HAVE ABOUT A 10 DAY PERIOD A MONTH WHERE I FEEL REALLY WELL AND I AM STRONGER AND I DONT FALL ALL THE TIME AND MY NEUROPATHY IS NOT CRIPPLING ME, BUT ARE THE SIDE AFFECTS I AM EXSPRIENCING NORMAL , ( OH I TOOK ASPERIN FOR HEADACHE WHICH IS SO BAD AFTER TREATMENT AND WORSE WHEN SOLUMEDROL WEARS OFF ,I THOUGHT I WAS GOING TO DIE ,NO ONE TOLD ME THESE DRUGS CAN NOT BE MIXED ,MY VISION PREVENTED ME FROM READING ABOUT IT
