I've just been to see my dermatologist because I've been dealing with incredibly itchy skin for the last few weeks - it feels like my entire body is on fire at times. The derm was great and recommended a topical cream that she is fairly sure will alleviate my issues. She wasn't comfortable diagnosing me officially without a biopsy but also wasn't sure we'd actually need one if the cream helps. I'm going back in 2 weeks to follow-up. Should I get the biopsy?
