What Causes Pins And Needles Sensation All Over The Body?

Hello there, over the past few weeks i have noticed that i have been getting very volatile outbreaks of itchy/prickly,w pins and needles sensations all over my body. It began to occur hen my body temperature rose and it was a little un-comfortable, the outbreaks would be around my upper body i.e; torso, arms etc. Initially i put it down to anxiety, but i had it checked and this wasn't it, also i knew i wasn't feeling anxious on anything. Now i'm beginning to get a tad worried, as the outbreaks have become far more frequent, and not only at times of temperature change, the sensations are far more un-comfortable, they've now become insanely painful and it results in me violently scratching all over to get rid of it. The parts of my body affected are now all over.



I haven't been using anything new on my body, in the form of; lotions, medication etc. Nor has my diet or excercise regiems changed, or my sleeping pattern. I don't put it down to clothing cause nothing is new there either. I'm genuinely concerned as to what it is, i'm currently waiting to see my G.P but i wanted to see if i could get some sort of idea here
