For the past couple of months, I have been experiencing feeling of pins and needles on different areas of body. It does not feel like when your hand or leg falls asleep, but instead like someone taking a needle and just pinching you with it. It can be in my arms, legs, stomach, hands, anywhere. When it happens I feel like I need to scratch it or rub it. I m very concerned because I don t know if it is pinched nerves, allergy or something else. It does not happen everyday but happening more and more. Has anyone experienced anything like this?
