At first I thought it was a vocal injury (it might be, I'm a singer), but I've realized the pain isn't coming from inside my trachea, its coming from what feels like a piece of cartilage on the left side of my trachea below my chin. The pain is mild/moderate, its fairly tolerable, but also random. Some days are worse than others, some times of day are worse than others. This has been going on for a couple of weeks now, my family doctor is booked full for the next while and I'm concerned.
