sick budgie? first time bird owner

Hi there, my budgie has been doing this thing for a while now where she will move her beak as if chirping or singing but with not a single sound. Appetite is ok, sometimes she'll concurrently grind her beak or stretch her wings or neck.

I was wondering if i should take her to the vet after reading more threads and learning this may be a sign of respiratory infection-- I have heard her sneeze a few times this week.

I've personally never taken her to the vet before and she's not hand trained--She's got some trauma around hands it seems I'm concerned that the stress of the vet trip might be too much for her.

Any advice appreciated, I'm kind of at a loss and want her to get better!
