For the past 2 months I have been having these sudden shooting pains in my upper right arm which sometimes switches between both arms, but it's mostly on the right and when it is , it's this shooting tingly feelings that shoots down my arm and down my back. Sometimes it will be alongside chest pain, sometimes it's mild and sometimes it's a little more intense ( but i think the chest pain is stress/anxiety related) I am 22 year old female no prior health disorders besides heart murmur and GAD (Generalized Anxiety Disorder). It just freaks me out and makes me think I am going to have a heart attack or Stroke. When the chest pain occurs i can also feel the pain in my back area. It seems like my arms always seem to have a "discomfort" feeling along with a numbness that doesn't seem to go away. But it's always just one side at a time. I guess I just need some reassurance that I am not having a heart attack or nothing of that sort. I will say that my anxiety is BAD and my stress level. As I am writing this now i got this really strong tingly feeling in my upper right arm, it's just going down the arm. My whole right side has a numb/discomfort feeling right now. Mostly my arm,neck, and head at the moment. Any idea what this could be ?? Any advice would be greatly appreciated! Thank you for reading.
