I have noticed about 4 - 7 days after taking this med. I have difficulty chewing on my left side of my mouth my jaw hurts so bad I don't want to eat.Anyone else experience this,it feels like the left side of my throat is abit swollen but my jaw actually hurts when I chew or move my mouth the wrong way.I have also felt the skin burning especially when driving the left arm & hand feel like they are on fire.
