I am so sorry you aren't feeling well.:(
It sounds like your achy arm symptom sparked anxiety/panic and things have just snow balled from there.:(
Try to look at these as separate issues. The ache could be anything from postural, to compression whilst sleeping, to an unknown injury...
...and these feelings have kicked up your anxiety regarding your heart.
Use your coping skills and positive mantras to help calm your anxiety...and I bet you will he feeling better again soon.
You are going to be alright.:)
