Hello, everyone!
My mother went through MVD, three and a half months ago, but she still suffering a lot. She has numbness and pain in her jaw and left cheek. She has also pain, but not constant. Sometimes she feel fine, but only for few hours.
She don't take any medicine because she's allergic.
I thought that she may have Anaesthesia Dolorosa, but she said she's not always numb and the pain is dull and not constant. Is that mean that MVD didn't work?
I'm very worried about her and feel very panicky. Please help!
Best of wishes to all of you!
