What Causes Palpitations And Rise Of BP During Tooth Extraction?

I am a 60 years old woman, weigh 62 kg, 5ft. height. I had a molar tooth extraction done on 1.9.11. The dentist gave me a second injection as the first one did not completely numb my mouth.After the second injection, I started to get a strange sensation in my feet and hands and also breathing problem. The dentist said I was having heart palpitation and gave me smelling salt to smell. After some time my breathing got harder and my BP was 100/175. Went to a heart specialist and had ECG and blood biochemistry done.Blood glucose-fasting 75mg/dl, blood glucose-pp 83mg/dl blood urea 28mg/dl, serum creatinine 1.1mg/dl, serum uric acid 7.7mg/dl LIPID PROFILE Total Cholesterol 174mg/dl, HDL Cholestrerol 34mg/dl,Triglycerides 270mg/dl,LDL Cholesterol 86mg/dl ,VLDL 54mg/dl.Total cholesterol Ratio 5.118. Presently taking Valent 40, zyloric,lipidcard-160,etirest-0.5.BP has come down but I still have an uncomfortable feeling in the middle of my chest and periodic feeling of not getting enough air in my lungs or faster heartbeat.Before this incident, I did not have any serious problem with BP. What else can I do, doctor? Please recommend dietry restriction to be followed. Thank you. Deki Yangzom
