Jenna, I'm so sorry to hear what you've been through.

Have you been seen by an ENT, Ear, Nose, Throat specialist?

These symptoms do not sound like PCS. Covid and other infections can cause strange symptoms like these.

Ask the ENT is a Neurologist assessment would be worthwhile.

Have you been assessed for PTSD? PTSD can manifest in strange ways. Your new anxiety could be a PTSD issue.

Have you had a thorough blood work-up? infections?
