It is difficult to judge or answer anything Botox related as there are no pictures. You feeling not well is definitely just virus related and I hope you feel better soon as almost everyone else is having the same symptoms. Botox does not migrate 2 weeks after being injected....
Hi there! I'm sorry to hear that you are having a reaction. It is unlikely that it is nerve damage. It sounds like it caused by the Botox injection spreading into areas it shouldn't. The good news is, if this is the case it will wear off in 3-4 months when your Botox does and will continue...
Although it is always possible to hit a nerve with injection, the most likely reason for your discomfort is a bit of bleeding into the muscle which will completely disappear on its own
