There is an implant failure in your left side of oral cavity.
generally when implant fails it dissolve the surrounding bone and the wound will become big and take time to heal.
there may be possibility that the nerve
which was passing from the area of infection may get involved and during the surgery to break the fusion it may get cut, which is causing you a feeling of frost bite
normally the miracle of nerve is that it regenerates in a due course of time.
tell your dentist
about your condition. he will put you on medication that can fasten the nerve recovery and healing.
