Yesterday, I was taken to the ER when after feeling an all over uncomfortable feeling for twenty-four hours I suddenly started shaking uncontrollably and while not hyperventilating like I normally do when I have a panic attack I instead found it difficult to draw any breath at all. It felt similar to when you have a congested chest, only it started suddenly. They wrote me a prescription for a new anxiety medicine and sent me home, however, after the medicine stopped the shaking I still had dull chest pain and was extremely nauseated.

Also, the day before that I was shopping when suddenly a sharp, intense pain shot from my right jaw down the side of my breast. It only lasted a few seconds, but I was almost doubled over with the pain.
This has happened before, and my doctor said it could be just stress related, but it's never this bad, and I've not been under any stress at all in weeks.

Today, I feel abnormally weak and am experiencing numbness on and off in different parts of my body. Sometimes it lasts in one of my arms for a few seconds, then my leg will suddenly go numb, even a part of my side went numb for awhile.

Could this all just be a form of panic attack that I haven't experienced before or is it possible that I could be mistaking something else for my panic attacks?
