Symptoms of an allergic reaction are different in different people. Also, I was experiencing the effects of a spinal cord leak at the same time....this is an important issue to note. Given all of that, the allergic reaction made me feel as though I wanted to jump out of my skin!!! I had burning sensations, vomiting, severe anxiety, an inability to seem to be able to take a breath, and all of this led to extreme dehydration. Because of this, my doctor has decided that I should never risk another steroid injection. If you think this is what happened to you, you should probably follow-up with your doctor. It is also possible that it is something else that the doctor could help you address. I would try to call and get an appointment within the next few days if I were you. Take care!!!!
