Three months after Nissen Fund surgery, throat problems?

Hi there, I had a Nissen fund surgery done 12 weeks ago. What is troubling me after post op is every day i have to keep clearing my throat most of the time. Around twice a week i have a sore throat for awhile, i am just wondering if this is normal and if anyone else has experience this after post op as I'm worried this surgery wasn't successful. if anyone can help, that would be greatly appreciated. thank you

Note: i'm not taking any medication at the moment.
