Q: How long do skin rashes typically last?
Rashes can last any amount of time, from minutes to hours, days to weeks, or even months to years, depending on the cause. The rash from hives, for example, may last only a number of minutes or hours. One individual hive lesion lasts for less than a day, but the general rash may last for weeks. Rashes such as psoriasis or eczema can last for months to years unless treated.
