My nose is still blocked even after 6 weeks of septoplasty. Is it safe to do septoplasty again now? Is there another option?

Nasal endoscope had been done for me after 6 weeks of septoplasty in another hospital not by my surgeon.Doctors told me that nasal septum is still deviated in the upper part and the surgery has to be done again for complete relief.But my surgeon repeatedly saying that my nose block is due to allergy and there is no connection with nasal septum. im confused whether to trust my surgeon or endoscope result.Please guide me whether i should undergo a surgery again?Or is there any other option?
