Reaction to Botox Delayed?

Botox last 3-4 months and if you would have had an allergic reaction it would be immediate. Most likely the two are unrelated but advise your health care provider. 

Best regards, 

You symtpoms don't appear to be related to your botox treatment. If you were going to have a reaction it would happen immediately after treatment. You can always come in to our office for a consultation to make sure you are treating it correctly. Best of luck

Getting a rash all over your body with hand/feet stiffness one month after neurotoxin injection is not a common side effect of the treatment. If you were in any way allergic to the neurotoxin, the symptoms would have manifested themselves earlier. It does sound as if you are having symptoms that need to be evaluated by a dermatologist, as further work up may be needed.
