I Developed A Blemish On Left Side Of Nose Which

I developed a blemish on left side of nose which hasnt healed followed by swollen, wrinkled skin under left eye. Recently the skin near left corner of mouth is red and swollen. This morning woke up with entire left side of face swollen, dry and itchy. Vision when reading has noticeably gotten worse. Itchiness is almost unbearable at times.
