Thank you for the replies I received re having Botox injections to help with droopy eyelids. My mum had the injections last Monday and I'm happy to report that they have worked. Her eyelids are no longer dropping involuntarily. I'm not sure how long it will last but it's a welcome relief for her. She said it didn't hurt and so far has not had any side effects.
We are over the moon. It's not often something works in this never ending conveyor belt of new symptoms and experimental medication brought on by this awful confounded disease.
