What Causes Pain In Finger?

Hi! A few weeks ago, I woke up with my right point finger painful. I thought it was because I had a bad sleeping position. A day after, there were like chickenpox-like spots at the bottom part of my hand and it was very itchy. It went on for about three days and I did not care much because I thought it was just an insect bite. On the days that followed, I noticed my point finger peeling until it got to my wrist. Until now it is peeling. Last night, I felt dizzy, nauseous - I do not have any history of lightheadedness and today I noticed my eyes are unusually red. It's red enough to be noticed really. I have always lacked sleep in the past few months and my eyes are never this red. What could this be? Does it sound dangerous? 1-10 with 10 being super red, well, mine is at 4.5 :(
