I had upper and lower jaw surgery 7 weeks ago. I"m 48 years old. What started as chin and lower lip numbness turned into terrible burning after about 7-10 days. I also have trouble speaking because they feel frozen. I also have a hard time eating because I have little control over my lower lip. Is the burning, needles, socks and other strange sensations because they are just damaged or because they are healing? Will this ever get better? After 7 weeks I am losing hope.
