Hi
Welcome to the MedHelp forum!
This could either be due to local cause like temporomandibular joint disorder or due to pinched cervical spinal nerve. You need to consult a dentist or a neurologist to find the cause. Take care!
Hey it could be TMJ It has so many areas that it touches. Mild case of ear or tooth ache, but it really come from your temporal joint. with spasm u can have that ache pain and the lips can feel tingly too. If u get anxious about it then it can worsen. Some times it can come from chewing a lot of touch stuff .Steaks, gum raw carrots.The numbness is just the nerves reacting Just like u said spasm it can truly be painful and frighting. I have had friends with this and they do get flare ups, So some advice stop all hard chewing 3 days will make a big difference just eat soft foods for a few days, warm hot towel around your neck and make sure u have a low flat pillow all this leads to a better relaxation of those muscles. and some people get it so bad they get servers headaches, glands on neck will ache , and all that is related to this. Their r TMJ specialist out there for u .So u can see to get a more medical opinion. Hope some of these tips works to get u feeling better
