Recovery from MVD surgery

Hello Everyone! So glad I found this site! After 4 yrs of mis-diagnosis, I had MVD surgery. I was elated to be pain free/drug free. Here it is 6 months out and the pain/electrical shocks returned to left forehead after sweeping, mopping, and vacuuming entire house. It is not as bad as it was, but very afraid it will become so. 2 mths ago I lost all sense of taste, the left side of my tongue became swollen making it hard to eat and swollow. And, of course, the left side of my face is numb and swollen. Is it possible all this is just part of the recovery process? Would so appreciate input from fellow TN sufferers.
