Another anxiety question about symptoms...

hi all,

just wondering about something, i get this weird horrible anxiety symptom (or what i assume to be a symptom) where i get a rush of adrenalin to my head, it feels horrible and then after that i can feel pins and needle type feelings all through my body – i’ve just had one and am now freaking out… but i’ve been getting them since i can remember getting anxiety, but am now worried it maybe something more sinister – does this sound like an anxiety symptom to you?

Thank you
