6 weeks ago I had an abscess under my arm drained and had to have the hole packed 3 x a week. I was then told I could change the dressing myself as it no longer needed packing. Half of the incision has healed nicely but the other half is still open with what looks like a lump of skin sticking out and it weeps a creamy fluid (doesnt look or feel infected/like pus). Does this sound normal?
