My daughter is 20 years old and has a terrible itchy rash mostly on her neck and chest area but also on her legs and torso. It started with small red bumps that we thought were spider bites. Each night they got worse. We have checked for bed bugs and found no signs to indicate an infestation. She went to a clinic and was told it could be scabies but they were unsure. I ve done a little research on scabies and my daughter has not been in close contact with any other humans recently. She does have a cat that sleeps with her and loves to cuddle and sleep on her head and chest. Thoughts?
