I have always experienced severe muscle aches in arms and legs during a flare, but recently my arms and legs feel very tense, like I am not in control of them. It feels like I have overexercised them. Does this make any sense?
I've had similar experiences, mostly in my forearms and thighs. It puts you in mind of the stiffness you get from overuse. My guess is that it's something to do with the tendons, maybe tendonitis? I've also had issues where a joint in my fingers would lock up in a somewhat similar fashion, so I assume it could happen elsewhere as well. Hope this may help some.:shrug:
Take care and I hope you start to feel better soon.
