Question: Information needed.

I have Dysport injections for Dystonia through Neurology Dept at local hospital, in my left shoulder.
I also have a Freestyle Libra 2 sensor, which I have on my right arm.
My question is :
If I move the sensor to my left arm, will this affect the Botox site ?

Answer: The FreeStyle Libre 2 sensor measures glucose in the interstitial fluid just under the skin, whereas Dysport is injected into the muscle. So, in general, wearing a Libre sensor on the left arm should not affect the Dysport injection or its effect.

However, I would avoid putting the sensor directly over or very close to a recent Dysport injection site. If you’re unsure exactly where the Dysport was injected, it would be sensible to check with your neurologist or the clinic that administers your Dysport.
