Been suffering with phlegm in my throat for 2 1/2 years. Was diagnosed with LPR, silent acid reflux. Meds did not help, had a cat scan, endoscopy, and sinus tests showed nothing . It is worse at night but always have the feeling something is my throat. Went to my GP, ENT, gastrologist no one was able to conclude or help me. It's depressing and don't know where to find help. I am imagining cancer that is being overlooked! It happened after my 3rd vaccine for covid! Any suggestions?
