What could have caused me to all of a sudden feel like I was passing out, so dizzy, sick to my stomach, heart racing when the dentist was giving me numbing shots to numb my teeth. He had already given me several shots with no problem, then all of a sudden everything went wrong. 5 days later I still feel light headed. No pain from the tooth extraction. I have had extensive dental work with no problems. He said he gave me something different in the shot but I was to sick to ask any more questions. I did not go to the doctor because I was afraid they would tell me I had a panic attack. It wasnt a panic attack, something went wrong in that chair. I couldnt even drive home I was so sick.
Hello, Welcome Thanks for consulting Chat Doctor, I have gone through your query, as you have mentioned in your query it can be due to Anxiety, or due to side effect of Anesthesia also.  Don't worry these symptoms last for few days after that you will be normal if it continues for week then consult your dental surgeon again and then go for any treatment.  Take proper sleep of 8 hours.  Do take proper nutritious healthy diet.  Do warm saline gargle two - three times a day. Hope this will help you.  Wishing you good health.
