I have been getting a burning sensation in one of my fingers though I experience pins & needles in others. I also get sharp shooting pains from my knuckles to my wrists. I also sometimes get what feels like a cold patch on my skin at my wrists. In the mornings in particular both my hands feel really weak though this wears off after about 20 mins. I have recently been diagnosed with hyperthyroidism which has given me such a wide range of symptoms; could there be a connection with this or should I be pushing for my GP to consider it separately?
