Why Am I Getting Pin Pricks Feeling In Hands And Feet While Laying Down Or Sleeping?
The causes of pinpricks in palm and feet could be due to
1. Peripheral nerve problem
2. Remote possibilities of spinal cord problem and restless leg syndrome
The first thing that is to be done is to get a clinical examination done. This examination is very crucial, as this will help us decide regarding the need of MRI scan of the spine to rule out a spinal cord problem. If there are no clinicaal signs of spinal cord involvement, he will require a nerve conduction test to rule out peripheral nerve problem. If this does not yield, you will have to subject him for a video-polysomnography to rule out a remote possibility of restless leg syndrome. These entire problem could be related to poor management of thyroid problem.
Please get evaluated by a neurologist and deal the way i have discussed above.
Hope this helps.
Please get back in case you have any doubts.
