Is there a name for this symptom

I've always called it numbness but I'm guessing that's not accurate as numbness is the void of sensation.

What I'm feeling is in my left arm and leg where it feels like either my arm and leg are being pulled and or they just wanna give up. If I left my phone to to my head there is like this slight resistance where my arm feels like it's just gonna drop, same goes for leg when walking... Does this have a name?
