Why am I aching all over?

[Pleasedontdothat]

For the last two days I’ve been really achy, especially across my shoulders, back and arms, but legs a bit too. I’ve not overdone exercising (and it’s a different kind of ache - more generalised), I haven’t slept in a funny position and I’m not feeling otherwise unwell. Any ideas what could be causing this?

Virus. We are achey in this house and all borderline lurgy.

TMI - I felt like I had been to the gym after having sex the other day. Nothing fancy, just a quickie but my thighs felt like I'd done an hour of squats. Honestly one of this years many many bugs.
