Hoping for some advice. Had a cold a couple of weeks ago. I thought it had mostly gone but now It feels as though I have really thick mucus/snot and the feeling as though it’s almost stuck on my tonsil (can’t see anything obvious when I look) also just the constant taste of snot type (sorry tmi) coming just from the one side. Any advice on how to break it down or get rid of it? Have tried decongestant, hot drinks, rinsing with salt.
