Sore Throat (Left Side) From Dirty CPAP?

I would consider myself a hypochondriac but here is what I am experiencing these past couple days.

On the left side of my throat I have had minor discomfort/soreness when swallowing only. I do sometimes produce some mucus build up and when I "hock it up" it has been just a whitish, mucus other than that I do not have any other issues or symptoms and feel fine other than this annoyance when swallowing. I also felt around my neck and jaw line for swollen lymph nodes and nothing feels out of the ordinary to me and it feels the same as the right side.

I do use a CPAP machine at night when I go to bed for moderate sleep apnea and I will admit that I need to make better habits and clean my CPAP equipment more regularly. I am hoping the sore throat is from irritation from a dirty CPAP, and now that I have cleaned it, drinking water, and taking over the counter medication (lozenge) that it will get better.

Of course when I research my symptoms online I see stuff that says not a big deal all the way to as bad as cancer related :(

Should I be worried with these type of symptoms? My anxiety is getting the best of me right now.
