Botox and a question of side effect
Botox usually takes 7-14 days for full effect. At this point 1 month after your injection, it is highly unlikely that Botox has anything to do with your symptoms. That being said, I do recommend you discuss the issue with your injector.

Generally Botox reaches its maximal effect 5- 10 days after injection. So it would be unlikely that it caused your symptoms.
One Month After Botox, Swelling & Pain At Injection Site - Is It The Botox?
Very very unlikely that Botox has anything to do with your pain and swelling. A reasonable guess would be that the needle itself caused a minimal scar band which snapped, and this localized irritation caused swelling. Obviously, this is a supposition on my part, but it is as good as any other.
I recommend you call your injector and see what he or she recommends. Thank you for this interesting question.
1 month s/p Botox
Happily, the neurotoxin in Botox is deactivated and removed from your body in about 4 hours. Even so, the effects last for about 90 days. It would be pretty unusual that a month after your injections you suddenly had symptoms at the injection site. If your symptoms persist, I would recommend that you return to the physician who injected you to see if they have any suggestions or answers. I would bet it's a completely unrelated issue, like allergies, or even an atypical migraine and not from the Botox injections.
