Deb, from all my research I have found that there are no medical professionals that are specialists in this area. I read a lot about botox for treating this, but the long term effects of repeated botox treatments are scary (muscle atrophy).
I am getting a massage this week by a person who is certified in trigger point massages. Believe it or not the pain can also be caused by tightness/knots in the neck and upper back that puts pressure on the trigemenal nerves. I have noticed that I am tighter on my right side than left and hoping that the massages will help. Right now the pain is not bad, but I would like to get rid of the source if it is the case.
