I was woken up by a pain in my arm that has me on the verge of tears. it's kinda more like an throbbing ache pain deep inside the top part of my trisc?

Many possibilities : Age, location (which arm), duration, provocative vs alleviating factors are all very important and missing factors that are needed to give you an accurate answer. The possibilities are endless with the information provided. Cramp, trauma, neuropraxia (depending on how you slept), all the way to indigestion vs angina (depending on many missing factors)
