<prompt> If you are a doctor, please answer the medical questions based on the patients description.I went to the dentist today. She stated she used septocaine. While giving administering the septocaine, sparks were shocking me and burning my tongue . After the septocaine wore out, my tongue is raw and there are puncture marks on my lips . Are there chemicals in spectocaine which could possibly have similar signs affects?  <response>: Hi, Septocaine is a local anesthetic which usually does not have any side effects until one is specifically allergic to it, which is a rare occurrence. While giving any local anesthetic there is a burning sensation in the area where the material is getting deposited, which is normal. If your dental procedure took a long time then the cracking of lips and raw tongue maybe due to constantly keeping your mouth open. Lips get Chat Doctor. If the discomfort persists or increases, I would strongly recommend that you consult your dentist. Regards
