21 years old with WHAT

So for the past 2 weeks my side has been super itchy. For the first week, it was super itchy but nothing was there. I was like okay there HAS to be something there! But, hubby said nothing was there. About 5-6 days later, this rash appears:

It is extremely itchy and PAINFUL. Last night I was sitting on the floor with my back against the couch. My dog went to jump on the couch and her clumsy ass missed and scratched my side. The pain was unbearable! I was in the fetal position doing everything in my power not to cry. Today, I go and see my mom who is a nurse and tell her everything and she tells me to just do ahead and go to the urgent care. Well, turns out I have shingles. Freaking shingles. Who gets shingles at 21 years old?!

Well, here goes the next couple weeks while I try deal with this nerve pain 😭
