What could cause tingling all over the body and when should I see a doctor?

You may feel a "pins and needles" sensation, which often happens when your nerves send mixed signals. This can be a sign of sensory neuropathy, where the nerves are not working properly due to irritation or damage. Many things can cause this, like changes in blood sugar, vitamin deficiencies, stress, or even temporary compression on the nerves when you sit or sleep in one position for too long. If the tingling is only occasional or happens after you put pressure on a part of your body, it might go away on its own. However, if you experience tingling all over your body that doesn't go away, becomes stronger, or is accompanied by other symptoms like weakness, numbness, or balance problems, it is important to see your doctor.
