Can I get another Botox shot even if ptosis from last injection hasn't resolved?

I didn't like nose flair and bunny line, tipping nose. university doctor injected 50 units of botox all over my nose. He diluted it with 2ml of saline. it migrated to my right eye. It has been '9' month and ptosis is almost gone but still recovering. need another injection to my bunny line and nose. 1. Will my posis fully go away? It is getting better 2. Should I wait until ptosis goes away? 3. can I assume botox in my nose area is still working since my ptosis hasn't gone
