Symptoms
By Mayo Clinic staff
Signs and symptoms of pyoderma gangrenosum include:
- Initially, one or more small, red bumps on your skin that resemble spider bites
- Painful, open sores (ulcers) with reddish-purple borders
- Achy joints or pain in your bones
- General feeling of unwellness (malaise)
The ulcers usually appear on your legs, but may develop anywhere on your body. If you have several ulcers, they may grow and merge into one larger ulcer.
When to see a doctor
Talk to your doctor if you develop unexplained blistering on your skin, an itchy rash or a sore that's slow to heal.
