There are a number of triggers for plaque psoriasis, and each person may have different ones. However, common triggers include:
• chronic stress
• time of year (more flare-ups occur during cold and flu season, as if those weren’t enough to deal with)
• certain medications (blood-pressure meds, anti-malarial drugs, and lithium to name a few)
• even a scratch or bad sunburn (one more reason to lather up and avoid the midday sun).Even the stress of reading answers and trying to figure out what webmd.com meant can trigger a flare-up (only kidding). If you have a flare-up, remember to tell your doctor about the circumstances preceding it. This could be helpful in preventing it from happening in the future.
