In most cases, your primary care doctor or dermatologist will be able to diagnose psoriasis by examining your skin. However, since psoriasis can look like eczema and other skin diseases, diagnosing it can sometimes be difficult.
If your doctor isn't sure whether you have psoriasis, he or she may order a biopsy. Your doctor will remove a small sample of your skin and have it looked at under a microscope.
You have a lot of options for treating your psoriasis. Along with medications, there are also simple ways to fight flares and ease your symptoms.
There's more research on psoriasis drugs, which are closely regulated by the FDA, than alternative treatments. But if you find a solution that works for you, it could be a great way to make your skin feel better.
