What causes pins and needles down my whole left arm?
Patient: Hi each night I am waking up with pins and needles down my whole left arm. it usually goes away during the day but comes back at night. it wakes me a few times each night for an hour or so. I work in a physically demanding job , with heavy lifting and using machinery. I am 40 years old and I smoke. I am 80 kg and 6ft1. I do regular sport 3 to 4 times a week Doctor: Hi,Thanks  for  your query.Your symptoms look like the features of nerve compression. You may take pain killers and if need be, tablet gabapentin, for this numbness. It is a stronger pain killer for neuropathies. Your doctor will know the doses.Also an X-ray cervical spine may help in diagnosis of any pathology there. Thus I would recommend that you see an orthopedic surgeon and get appropriate investigations done including vit B12 levels in blood.I do hope that you have found something helpful and I will be glad to answer any further query.Take care
