Can pressure from a snorkel mask on my forehead cause any migration problems after botox injection 4 or 5 days ago?

I had botox in forehead 5 days ago, today I am snorkeling/diving with a mask. Can the mask pressure cause any botox migration issues to my eyes ? My doctor said no rubbing my forehead for 3 weeks, which sounds excessive. Does it migrate after the first day after injection?I tis already working in my forehead. Thanks!! I am on vacation and really want to go snorkelling
