question: Dear Doctor, My fourteen year old daughter has for the past three weeks reported the sensation of pins and needles in both her arms, hands and legs. My husband took her to our GP as we thought she may have a trapped nerve. We've in the past paid for chiropractic treatment to help with her poor posture. The GP requested a check of her bloods with a fasting blood test and I'm releived to report that these are clear.  My daughter has since reported periodically smelling dirty nappies nad burning, often asking friends and family if they can smell this. The GP has asked that we keep a diary for two weeks. We haven't made her aware of the these smalls so I will do that shortly. Any advice would be very much appreciated. Kind regards Claire Cooper
