Can pins and needles just be pins and needles in a diabetic, just like in normal folks?

Yes, but... Anyone can get a pins and needles sensation, diabetic or not, which is harmless and typically lasts seconds to minutes. However, diabetics are more likely to develop neuropathy, or nerve damage, which can feel like pins and needles. This typically develops in the hands and feet. Anyone with diabetes and pins and needles should visit their doctor for evaluation.
Yes. One can have "pins and needles" just like a non-diabetic, or it can be associated with diabetic neuropathy.
Could be. Neuropathy is a condition resulting from abnormal nerve function. Neuropathy can be due to certain vitamin deficiencies, nerve damage due to trauma, alcohol consumption, radiation, side effects of certain medications, or due to certain medical conditions such as diabetes. Treatment varies depending on the cause of the problem. Have it evaluated and appropriately treated.
