is rash common?

i recently got diagnosed about a month ago. and i get rashes after the shower which i found out is normal with pots. but i randomly break out in rashes on my chest and sometimes my cheeks get very flush and i get butterfly rash. it happens mostly when im in the sun but sometimes its random when im at work in the office all day. my rheumatologist told me shes testing me for lupus next month but she said it could be a symptom of pots. i’m still learning a lot about pots and google isn’t much help. i just want to know if this is common.
