Spasticity

I have found recently when yawning my spactisty is worse and my right arm and hand cramps up and 'twitches', has anybody experienced this?
@Stumbler

@bradleystaff , I think you may find that it is an involuntary reflex action to stretch certain muscles when you yawn. This can lead to cramps and "twitches"..............

@bradleystaff, Yes I can relate to your symptoms, when I yawn my right hand curls into a fist. It's the same as trying to walk when you yawn or sneeze I can't do the two at the same time.
