Left arm doesn't feel like my arm!!

[LaceyAnne]

Heyy, so recently I've been feeling like y left arm isn't my arm. However it's not numb as I can feel pain and can move it around like it's mine, it just kinda feels not there if I don't focus on it, anyone have any advice or know what it is??

Please I'm freaking out!

I've been dealing with the same thing for quite awhile, for me it's usually worse if my breathing is off or if I didn't get enough sleep. I usually been distractinh myself from it but any other advice would be helpful as well.
