I had an injection of lidocaine kenalog this morning and almost immediately lost muscle control and became drowsy. My head, face and throat went numb, my chest was tight, and I almost passed out. The doctor and nurse said that they had never seen this reaction before and attributed this reaction to low blood sugar (I have no problems with my blood sugar). It is now several hours later and although I feel much better, I am still dizzy and my chest still feels heavy. What should I do and can I trust this doctor again?
