The first two symptoms I had that eventually pointed to PN were difficulty swallowing and dizziness. After a basic blood test I saw the ear nose and throat doctor. I had some fluid in my ears, but it didn't end up being the cause of the dizzines. Other tests were also negative.

My acid reflux was suspect for the throat swallowing issue. I had an upper GI about a year before these symptoms showed up and all was normal. So they did an esphogram which consists of swallowing barium and watching it on a monitor. Also normal. (Please note this test is not as reliable as an endoscopy/upper GI)

The tingling in the toes and hands followed shortly thereafter.

Now about 2-1/2 years later I know my body much better. When I get a flare up, symptoms are a mix of all of these PN traits. Not necessarily all of them at the same time, but combinations of them that vary with each flare up.

Fortunately the swallowing issues don't come on much anymore. If it does, then it only lasts a day or two. Same with the dizziness for the most part. There are exceptions in duration, but they are rare.

Difficulty swallowing is a huge concern. It could be a sign of esphogus cancer. It is rare, but deadly. Please have it checked out. An endoscopy is definetly the way to go for testing. Good luck!
