7. Hello! I have seen several nasal sprays on the market and some of them stated that it is either suitable for sinusitus or hayfever and cold; while the others stated that is it suitable for sinusitus, rhinitus and allegies. Should I buy the latter one if I have a nasal polys or some kind of infection?
