Can stress cause rashes and hives?

Stress is one of the known triggers to cause rashes and hives.  The best way to manage the breakouts is to develop a good stress management plan.  Over-the-counter products are available to help control the symptoms during a breakout, but do not start any new medication, topical or oral, before discussing it with your physician.  Discuss your symptoms and concerns with your physician.  He or she can also order allergy tests to ensure that there is not an environmental cause for your breakouts.
