I scraped my finger and it looked like it was healing but then it started getting swollen and stiff with little blister-looking bumps. It's sensitive to touch but for the most part doesn't hurt. I just want to know how to completely heal it. :(

More details: It's been about a week since I hurt it. I scraped it on a wooden table. It dosnt feel warm to the touch... I haven't had a fever. The blisters look unusual to me... They are slightly transparent and I can see there are smaller bumps inside the larger swollen part.
