Burning in my chest and throat and nausea. Possible Botox side effect?

I went to the gym 2 days after my Botox injections and had to leave because I had a rapid heartbeat, shortness of breath. This has never happened to me. Couldn't it be a result of the Botox?

This is not an expected side effect of receiving botox. Please consult with your primary care provider.

Best of luck !
