Botox side effect? I've had it twice before

I would say that it is likely that the nausea you are having, 2 days after the Botox treatment to your forehead, is not related to the Botox.  Rubbing your forehead after the treatment is also not likely related to the nausea.  I would consider seeing your primary care doctor if the nausea does not improve, so that a cause can be determined.

Rubbing your forehead after Botox injections should not give you  any nausea, vomiting or stomach problems. Botox is probably one of the safest cosmetic treatments available. So relax and enjoy your wrinkle free forehead!

Botox is the most popular cosmetic injection done in the United States today. It is highly unlikely that your feelings of nausea are related to your Botox injections. It is much more likely that you contracted a virus of some type or "stomach bug".  Rubbing your head after Botox would have no such reaction.  Please keep us posted. Best, Dr. Green

Although the timing of your Botox treatment and the onset of your feeling nauseous makes one question if the Botox caused your symptoms, it is likely unrelated. As you know, nausea and having an upset stomach can be caused by a myriad of things. You could have eaten something that disagreed with you, or you could be coming down with a viral bug. The fact that you have had Botox before without feeling ill, strongly suggests something else has caused your symptoms. Rubbing your forehead did not cause your symptoms. If your symptoms worsen or persist, please seek medical attention. I hope you feel better. 

THe side affects of Botox are not stomach sickness  and nausea. Its likely you are getting ill from another cause and the Botox injections being a recent treatment are just an incidental finding.If this continues see your physician but the Botox as a culprit is likely not.

Developing nausea and stomach issues two days after botox are most likely conincidental.  Botox is a very safe medication when injected by a trained professional.
