Why Do I Have Dry Itchy Rashes At The Back Of My Neck?
Different possible causes
The most common reasons for dry, itchy rash would be (1)fungal rash (2) allergic local skin reaction
If the area has a circular appearance with slightly raised edges then it maybe fungal and using an anti fungal cream such as ketoconazole or miconazole or econazole may help. For the first 2 to 3 days a mild steroid cream can be added.
It can take 2 to 3 weeks for a fungal rash to improve
If the rash is a local allergic skin reaction then treatment would be with a steroid cream such as hydrocortisone. This is one of the weaker steroids so if it is not effective then your doctor may need to prescribe a different one
I hope this helps, feel free to ask any other questions
