Hi Doctor , My Finger Next To The Thumb Got

Hi Doctor , my finger next to the thumb got trapped whilst extinguishing a fire and then hot wax also poured on it and then I applied running water and burnol . The emergency section of hospital gave me TT injection and Taxim tablets for a week and asked me to leave the burn as it is for few days as small water sacks had developed . Now I am using silverx but the finger is quite rigid and I feel some water is still there in the skin and thick skin has formed above it . I am concerned that the finger is less flexible and burnt too which looks ugly . Please advise . Best Wishes , Chubbie
