Thanks for your response Kenny, and i fully agree with your comments relating to a diagnosis. Experience of others, such as you have helpfully provided, is what I'm after. My tingling doesn't stop me from sleeping, its just like pins and needles at the moment, though i notice it more at night. Do you mind me asking about other symptoms? The last time i spoke with my doctor they sent me for investigations for dysphagia, all of which came back clear. Google has now mentioned that it might also be a diabetic symptom.
I will speak to my doctor as soon as i am able to arrange an appointment.
