Pins and needles in left hand

Pins and needles in left hand a month ago and a very dull ache in forearm , the ache has stopped but the pins and needles occur around once an hour every day , Dr said it was from a sore neck, but would that go on for so long?

Yes,it could. Although your doctor has described it as a sore neck it is very likely that you have a pinched nerve somewhere,possibly in your neck. If it continues,ask your doctor if he can recommend exercises that would help or maybe some physiotherapy
