Unknown head / face pain

New here. Last year after I had my son, I lost several pounds by exercising, high impact cardio work outs at home--usually on the fly when the baby napped and of course no sneakers. A few months later every time I would exercise I would end up with a hoffic right sided headache and face pain shooting down to my neck and sometimes I feel tingling in my right leg as well. My right temple would indent, my right eye would buldge out. I went to a specialist and he told me I had neurolgia of some sort and muscle spasms. I had some treatment with a needle but then I had to return to walk and never finished the treatment up. I dont remember the drug I was given for the injection. I stopped all excerise last Summer and eventually the horrible pain went away. I restarted my excerise program this month (a year later) and all of a sudden I had another attack of the same exact thing. I had to stop all exercise and now the pain and the indent in my temple started to go away. I took a walk today and it started up again but not as bad. I call these episodes and the pain is really awful along with the indent and the eye buldge all on the right side. Any idea of what this is? I am starting to get concerned. To make matters worse during the time all these episodes came along I had 2 root canals on the right side and I als fell and hit my head on the right side on a hard floor when I carried a baby saucer down the steps. And I do have TMJ as well. All of these things happened last summer when the pain started on that side of my head.
