My throat is extremely dry all the time 6 months after septoplasty, is this normal?

I had a Septoplasty in April this year, all went well and I now can breathe a lot better through my right nostril, since this surgery and has got worse as the time gone on. My throat is extremely dry all the time, I cannot produce any mucus on the right hand side and to be fair I have very little on the left which makes my throat extremely dry that it feels like I have an obstruction/narrowed? Is this normal or is there anything I can do to help? Thank you I’m advance. Craig
