Hello,
U can use flutiflo nasal spray for longer period of 3 months but with that u needs to do gargles 10 min after every time u take the spray.
The back side headache is more or less not associated with the sprays if it severely affects your day to day routine than u should consult a doctor to identify the main cause of headache.
