I had a stroke. How much will Botox cost for the arm and leg?

If you had a stroke and are at loss for movement, this would not be the treatment for you as botox will make it worse.  Best, Dr. Emer.

Thanks for your
question – and you need to make an appointment with a specialist in using Botox
for these areas – but most of us would recommend caution here and if the
muscles in the area are already weak, Botox may worsen the situation. Learn
your treatment options and proceed cautiously.

Botox inhibits specific muscle movement so I'm not sure what you are looking to do exactly, but in no way should you be having Botox injected into a full arm or leg. This would not be ok or a good idea. "This
