Thanks for you query.
It is quite usual with many people to get pin and needle sensation along with numbness
in any part of body. It shows blood supply or nerve
supply to that are is compromised little bit. It is usually caused by bad posture or pressure causing compression of vessels and nerves and it may accompany muscle/tendon strain.
It is more common in fatty or lazy people. Beside that, numbness and needle sensation is common in persons having vitamin B12 deficiency
which is associated with anemia
I advise you to exercise regularly and avoid bad postures during sleep. Use comfortable bed and keep changing position during sleep.Take Vitamin B12 supplements and have good diet. It would be better to evaluate you blood by CBC, if it shows any anemia then go for Vitamin B12 levels.
If problem persists, visit your doctor.
Hope it helps.
