I have a 10-in 35-year old scar from a colon resection. (perforated Crohn s). The Crohn s came back 10-yrs ago. I am on weekly injectable Methotrexate. My scar has started weeping in a couple of spots (where we had slowed healing to allow drainage. Say 2.5in. of the scar is red, weeping, irritated ... not pussy, not blood, not open ... but wrong , moist ... painful to touch. Thoughts?
