Hi.  I'm thinking about getting the botulinum injections and would love to know more about them.

Botulinum is a toxin produced by the bacteria Clostridium Botulinum.

Sounds a little scary, but I know people that have had it done and really like the results.

It can be used for therapeutic purposes. The first such use was to treat strabismus in 1981.

Oh wow, really?  Is strabismus the weak eye thing?

Yes. Botulinum works by blocking neural impulses from muscles, and so causes muscle paralysis. This can be helpful in conditions where muscles are overactive.

That sounds really interesting.  What about restless leg syndrome?  Can it help with that?
