Suggest Treatment For Anxiety And Numbness In Hands

I don’t know what condition I have. Over the past 2 years I have been having “anxiety” episodes, I don’t even know if it’s anxiety, but it’s the way i feel when I get these episodes. It was usually during the night, I would not sleep at all because I would feel very anxious but the problem with me is not mentally (I think) but physically; my hands/arms. When I have these episodes my arms feel funny, like numb, I feel so frustrated and start punching things and often I open and close my fists really hard. I don’t have shaky hands because my hands don’t shake, I am the one forcing my hands to shake violently because of this weird feeling in my arms that makes me so frustrated and desperate whenever I have these episodes.
