Feel sensation in my chest by my heart. have an abscess tooth being treated by clindamyacin. feel fine, smoke n drink also have anxiety should i worry?

Yes: Your life style places you at risk. Antibiotic will control spread of infection but will not cure abscess...tooth needs root canal or extraction. Call your PCP re: chest sensations. See Dentist to Rx tooth.

Follow up: With your health history and habits I would complete the treatment and go back to the dentist for any follow up and additional treatment needed. You should not worry too much as long as you follow your dentist recommendations. Take it easy.

You should: Pain in your chest is a serious medical condition. It is always a red flag and appointment with your PCP is warranted, especially if you smoke and drink. See your doctor for further investigation, tests and treatment. A tooth abscess or gum abscess won't go away without dental treatment. See a dentist for evaluation and x-ray. And yes, quit smoking and drinking.
