I'm have intense chest tightness ten days after application of Botox to forehead. When will this symptom stop? Why it happening?

Thank you for your question.  It is always advisable with complaints of chest tightness to have yourself evaluated by a medical professional to determine the cause.  This could be a very serious symptom, and its cause should be determined.

Its unlikely that your symptoms are related to your botox treatment.  You should seek an urgent medical review to determine the cause of your chest pain.

I don't believe this related. I have read the product monograph and nothing like this is reported. You may have something more serious and need to see your primary care physician or ER to ensure something more serious isn't going on."This answer has been solicited without seeing this
