Hi , I'm having this constant nearly all day vibration sensation in my left leg (feels like a blood rush). Sometimes in hand also. Also feets are getting numb while I sit on folding leg position (while for lunch/dinner) . I was very low on  vit D3 and b12 in march at that point I had prescribed medication as I was feeling tingling ,joint pain and burning sensation in hand and feet but with medicine I recovered and by June it was all normal. During these period I also tested for diabetes and thyroid both came negative. But this vibration sensation never got cure fully it was there on and off sometimes all this while but now for last week or soo its like all time there . Note - I have cerebral plasy by birth hence a weak right side of body (hand and leg don't are weaker) Please, advise.
