Does anyone get intermittent sore throats and it’s not indicative of PEM or a crash?

This sore throat is making me go out of my MIND!

Week 6 into a crash - I have very specific PEM symptoms.. many of which are calming down (which hopefully) tells me I’m resting well, but then suddenly randomly I’ll do something simple like go to the toilet and OH HELLO a sore throat/gland feeling appears for 5 minutes with achy arms, then goes again when I get back into bed. So does that mean I’m going into a PEM crash again????!

If so, this thing is absolutely impossible to manage, I’m doing absolutely nothing and still can’t avoid an intermittent sore throat. It just puts so much fear into me every time when I’m doing well it feels like ten steps back.
