Does "creating headaches " mean "making troubles"?

Context:
Ever since the first iPad was released in early 2010, physicians have been adopting tablet devices in droves. According to a survey by QuantiaMD in May ’11, 80% of physicians surveyed owned a smartphone or tablet and 30% owned a tablet device. And from this individual adoption, physicians are increasingly using their mobile devices in their clinical duties, creating headaches for many IT managers out there.

Yes, in this context the iPads are making trouble for IT managers.

Note: Trouble in this context is always singular – when pluralised, it means things that are stressing/worrying you, as in "He told me of his troubles".

Thank you.

Does " many IT managers out there" mean " many IT managers in their hospitals"?
