People with mild rosacea might not even ask their doctors about it. But whether you have been diagnosed with rosacea or not, there are some signs you shouldn't ignore. You should see your doctor if:

You have just developed symptoms, such as facial redness. Rosacea can look like some other serious diseases, so it's important to get a proper diagnosis to rule them out.

You have developed bumps, pimples or visible blood vessels -- small red, purple or blue lines -- on your face. These can be signs of worsening rosacea. It's important to get treatment before your condition advances further.

Your rosacea symptoms are causing you anxiety or embarrassment. It's very common for people with rosacea to become ashamed of their appearance. However, don't surrender to your condition. There are treatments that can help.

Your eyes are affected. Many people with rosacea have eye symptoms. They might be dry, itchy, painful, or bloodshot. Your eyelids might be red and swollen. Untreated, these symptoms can sometimes lead to serious eye damage.

Your nose has become swollen and red. This can be a sign of rhinophyma, which indicates advanced rosacea. It's more common in men than women. Although rare, if left untreated, it can lead to permanent disfigurement.

10 Questions to Ask Your Doctor About Rosacea

Once you see your doctor, make sure you understand both your condition and its treatment. Here are some questions you might ask:

• Should I be referred to a dermatologist?
• Are you sure I have rosacea and not another condition?
• What type of rosacea do I have?
• What foods and drinks should I avoid?
• Could any medicines I'm using be causing my symptoms?
• Do you have recommendations for what soap and skin products I should -- and shouldn't -- use on my face?
• Do you have suggestions for cosmetics I could use to cover up my rosacea?
• Do I need to use ointments or take medicines? What are the side effects?
• How long will it take for my treatment to work?
• What will you try next if my current treatment doesn't help?

Do your part to keep your rosacea under control: Ask questions, track your triggers, and stay informed.
