Just started taking Xonvea first dose (2 tablets) last night, today I am like being run over by a car which is apparently normal, but concerningly, one of my arms is hurting like a heavy object has struck it (upper arm only). I don't think i've lifted anything heavy, nor slept funny. So was wondering if anyone felt that when they started taking xonvea? I've requested a GP call back to discuss but just wanted to hear anyone who may have had experience (or not) of this side effect of the drug. Thanks!
