I've been feeling that my throat is dry for almost 3 weeks now even when I drink water. Last week, it was also a bit painful. Now, the pain is gone but I still feel like my throat is dry like it's got sand around it. Also, yesterday, my lips suddenly became swollen and even when I apply colc compress, it would not subside. Before, when I lack sleep, one of my hands would get really swollen, is this a sign of stress?
