about 6 weeks ago i started having odd sensation in my throat. Prior to that I had taken thermogenic fat burner for two weeks.
Went to dr who suggested taking gaviscon for 2 weeks. I started this plus Nexium
It went away. But recently came back.
Stressed out with worry
You might not have taken enough water after you took the fat burner pills. I had a supplement pill stuck in esophagus before without knowing, and developed a burning sensation in my throat for 5 days. Dr gave me a PPI too. It went away after the esophagus healed.
Try stopping the supplement, and switching to something like exercise. Good Luck
