I had only one finger at about 35-40 degrees when I had the NA performed about 4 weeks ago. I am surprised at how much it still itches. Itching was expected, just not so much for so long. Mostly it is centered 3/4 of an inch towards the finger from the insertion point. This is where the most deformity remains; the contact point of my palm where a bump (callous?) formed before the NA. The finger is straight and from the pictures I have found this is normal. I believe it must be a "collagen bump" and it will stop itching for a minute or three after I rub/massage it.

Hopefully that is enough detail to answer the question; will it stop and/or decrease and how soon?
