on nov. 10 2006 I had recieved anintra-articular kenalog with marcaine injection in both knees. I had a minimal allergic reaction to cortisone a few years ago which benadryl fixed the problem. I reminded my ortho doctor of my allergy he said kenalog is in the same family but should be ok. Stupid me took the shots beliving him and physicans assist. that it would be ok. that night i couldnt sleep and was swetting real bad. and i woke up with a headache. next night same thing until about 5am I turned deep red purple and felt very anxious. I again took benadryl. a little time passed my leg mussels were jumping vision blurred head really hurting and still red and purple skin from the chest up I called my ortho dr. he said well how do your knees feel? I was pissed. i went to the ER. my blood pressure was 184/101 heart was racing i felt like crap. They gave me intraveinous benadryl and pepcid watched me for a few hours then I went home. had bad stomach cramps that night and I still feel like crap. what is the number of the drug company ?? why didn't my doctor tell me the side effects?
